Chapter 1: Introduction to Punctuation

Punctuation is the silent scaffolding of written language, a system of symbols that organizes words into meaningful structures, guides readers through sentences, and shapes the tone and intent of communication. It is not merely a set of arbitrary marks but a critical component of grammar that ensures clarity, enhances flow, and conveys the writer’s voice. Without punctuation, even the most eloquent prose would collapse into a jumble of words, leaving readers confused and disconnected. This chapter introduces the definition of punctuation, explores its indispensable role in grammar, and examines how it fosters clarity, maintains flow, and modulates tone in writing. By understanding these foundational principles, readers will gain a deeper appreciation for punctuation’s power and learn to wield it effectively in their own work.

Defining Punctuation

At its core, punctuation refers to a standardized set of symbols used in writing to separate, organize, and emphasize elements of text. These symbols—such as periods, commas, question marks, and colons—act as visual cues that guide readers through the structure and meaning of sentences. Punctuation is not a modern invention; its roots trace back to ancient civilizations, where scribes used rudimentary marks to indicate pauses or divisions in texts. For example, in ancient Greek manuscripts, a dot known as a stigma was used to separate words, a precursor to modern punctuation. Over centuries, these marks evolved into the sophisticated system we use today, standardized across languages to ensure consistency and universality.

Punctuation serves as the grammar of written communication, complementing syntax (the arrangement of words) and semantics (the meaning of words). While grammar rules dictate how words are formed and arranged, punctuation provides the pauses, stops, and connections that make those arrangements intelligible. Consider the difference between these two sentences:

- I have two cats they are fluffy.

- I have two cats. They are fluffy.

Without the period, the first sentence is a run-on, forcing the reader to parse a continuous stream of words without a clear break. The period in the second sentence signals a pause, separating the two ideas and making the text easier to follow. This example illustrates punctuation’s fundamental role: it structures language to mirror the natural rhythms of speech, ensuring that written communication is as clear and intuitive as spoken words.

The Importance of Punctuation in Grammar

Punctuation is inseparable from grammar because it reinforces the structural integrity of sentences. Grammar provides the rules for constructing sentences—subjects, predicates, clauses, and phrases—but punctuation ensures those components are presented in a way that readers can understand. Each punctuation mark has a specific grammatical function, whether it’s marking the end of a sentence (period), separating clauses (comma), or introducing a list (colon). By adhering to these functions, punctuation helps writers convey their intended meaning without ambiguity.

One of punctuation’s primary grammatical roles is to delineate sentence boundaries. Sentences are the building blocks of communication, and punctuation marks like periods, question marks, and exclamation points signal where one sentence ends and another begins. This segmentation is crucial for clarity, as it prevents ideas from blending into one another. For instance:

- She loves to hike she climbs mountains every weekend.

- She loves to hike. She climbs mountains every weekend.

The period in the second example clearly separates two independent clauses, allowing readers to process each idea individually. Without this boundary, the first sentence risks overwhelming the reader with too much information at once.

Punctuation also governs the relationships between clauses and phrases within a sentence. Commas, semicolons, and colons, for example, indicate how ideas are connected—whether they are equal in weight, subordinate, or explanatory. Consider this sentence:

- I wanted to attend the concert, but I had to finish my homework.

The comma before “but” signals a pause and introduces a contrasting idea, reinforcing the grammatical structure of a compound sentence. Without the comma, the sentence would still be grammatically correct, but the pause adds clarity and mirrors the natural rhythm of speech.

Beyond sentence structure, punctuation interacts with other grammatical elements, such as verb tense, pronoun agreement, and word choice. For instance, quotation marks clarify when a speaker’s exact words are being reproduced, ensuring proper attribution and maintaining the integrity of dialogue. Similarly, apostrophes distinguish between possessive forms and contractions, preventing confusion between words like “its” and “it’s.” By working in tandem with grammar, punctuation ensures that written language is precise, coherent, and expressive.

Punctuation and Clarity

Clarity is the cornerstone of effective communication, and punctuation is one of the most powerful tools for achieving it. By organizing words into logical units, punctuation helps readers navigate complex ideas without getting lost. It acts like a roadmap, guiding readers through the twists and turns of a sentence and ensuring they arrive at the intended meaning. Without punctuation, even simple sentences can become ambiguous, leading to misinterpretation.

One famous example of punctuation’s role in clarity is the sentence “Let’s eat Grandma.” Without a comma, it suggests a shocking cannibalistic intent. With a comma—“Let’s eat, Grandma”—the sentence becomes a friendly invitation to dine. This example, while humorous, underscores how a single punctuation mark can dramatically alter meaning. Commas, in particular, are essential for separating elements in a sentence to prevent misreading. For instance:

- The panda eats shoots and leaves.

- The panda eats, shoots, and leaves.

In the first sentence, the panda consumes plant shoots and leaves. In the second, the addition of commas transforms the panda into a gun-toting creature that eats, shoots a weapon, and then departs. This illustrates how punctuation can resolve ambiguity and ensure the writer’s intended meaning is clear.

Punctuation also clarifies complex sentences with multiple clauses or phrases. Consider this example:

- After finishing her homework Jane went to the park to meet her friends who were playing soccer.

Without punctuation, the sentence is a dense block of information that requires careful parsing. Adding punctuation breaks it into digestible parts:

- After finishing her homework, Jane went to the park to meet her friends, who were playing soccer.

The commas separate the introductory clause and the nonrestrictive relative clause, making the sentence easier to follow. By providing these pauses and divisions, punctuation ensures that readers can process each component of the sentence without confusion.

Clarity is especially critical in professional and academic writing, where precision is paramount. Legal documents, scientific papers, and business reports rely on punctuation to convey exact meanings and avoid costly misunderstandings. For example, a misplaced comma in a contract could change the scope of an agreement, leading to disputes. Similarly, in academic writing, colons and semicolons help structure arguments and present evidence clearly, ensuring that complex ideas are accessible to readers.

Punctuation and Flow

Flow refers to the rhythm and pacing of writing—how sentences move from one to another, creating a seamless reading experience. Punctuation plays a pivotal role in establishing this flow by mimicking the natural pauses, emphases, and transitions of spoken language. Just as a speaker pauses for breath or emphasizes a word to convey meaning, punctuation provides the written equivalent, guiding readers through the text with ease and grace.

Commas, for instance, create brief pauses that allow readers to absorb information before moving on. In a list, commas separate items to prevent them from blurring together:

- The grocery list included apples, bananas, oranges, and grapes.

Without commas, the list would be a chaotic jumble, forcing readers to slow down and untangle the items. By providing clear divisions, commas maintain a smooth flow, allowing readers to glide through the sentence effortlessly.

Semicolons and colons also contribute to flow by connecting related ideas in a way that feels natural and cohesive. A semicolon links two independent clauses that share a thematic connection, creating a sense of continuity:

- She loved painting; her canvases were filled with vibrant colors.

The semicolon allows the second clause to build on the first, maintaining the reader’s momentum while highlighting the relationship between the ideas. Similarly, a colon introduces information that elaborates on what came before, creating a forward-moving progression:

- He had one goal: to win the championship.

The colon propels the reader from the general statement to the specific outcome, enhancing the sentence’s flow and focus.

Dashes and parentheses, while more informal, also influence flow by adding variety and texture to sentences. A dash creates a dramatic pause or interruption, drawing attention to a particular idea:

- She was about to leave—then she remembered her keys.

The dash mimics the abrupt shift in thought, keeping the reader engaged. Parentheses, on the other hand, insert supplementary information without disrupting the main flow:

- The conference (held annually in Chicago) attracts thousands of attendees.

By enclosing the extra detail, parentheses allow the reader to continue with the primary sentence while still absorbing the additional context.

Effective flow is not just about readability; it’s about creating a rhythm that mirrors the writer’s intent. Short, punchy sentences with periods create a brisk, urgent pace, while longer sentences with commas and semicolons slow the tempo, allowing for reflection. By mastering punctuation, writers can control the ebb and flow of their prose, crafting a reading experience that feels dynamic and purposeful.

Punctuation and Tone

Tone is the emotional or stylistic attitude of a piece of writing—whether formal, conversational, humorous, or authoritative—and punctuation is a key tool for shaping it. Each punctuation mark carries an emotional weight or stylistic nuance, influencing how readers perceive the writer’s voice. By choosing the right punctuation, writers can convey excitement, hesitation, confidence, or irony, adding depth and personality to their work.

The exclamation point is perhaps the most obvious tone-setter, signaling enthusiasm or urgency:

- What an incredible performance!

The exclamation point infuses the sentence with energy, conveying the writer’s excitement. However, overuse can dilute its impact, making the writing seem overly dramatic or juvenile. Writers must use exclamation points sparingly to preserve their effect.

Question marks also shape tone by introducing inquiry or uncertainty:

- Are you sure about that?

The question mark creates a conversational, engaging tone, inviting the reader to reflect or respond. In contrast, an indirect question without a question mark shifts the tone to a statement:

- She asked if I was sure about that.

This version feels more formal and detached, illustrating how punctuation can subtly alter the writer’s voice.

Commas and dashes contribute to tone by controlling pacing and emphasis. A series of commas in a long sentence creates a measured, deliberate tone:

- The old house, with its creaking floors, dusty windows, and forgotten memories, stood silently at the edge of town.

The commas slow the pace, evoking a reflective, almost melancholic mood. A dash, by contrast, can create a conversational or dramatic tone:

- The old house—creaking, dusty, forgotten—stood silently at the edge of town.

The dashes add urgency and focus, making the description feel more immediate and vivid.

Quotation marks can also modulate tone, particularly when used to indicate irony or skepticism:

- His “genius” plan failed spectacularly.

The quotation marks around “genius” signal sarcasm, suggesting that the plan was anything but brilliant. This use of punctuation allows writers to convey subtext without explicitly stating it, enriching the tone with nuance.

Punctuation’s impact on tone is especially evident in dialogue, where it captures the cadence and emotion of speech. Consider this exchange:

- “I can’t believe it,” she whispered. “It’s really happening.”

- “I can’t believe it!” she shouted. “It’s really happening!”

In the first example, the commas and periods create a quiet, introspective tone, while the exclamation points in the second convey excitement or disbelief. By manipulating punctuation, writers can make dialogue feel lifelike and emotionally resonant.

The Evolution and Universality of Punctuation

Punctuation is not static; it has evolved over time and varies across languages and cultures. In English, the modern punctuation system began to take shape in the Middle Ages, with the introduction of the comma, period, and question mark. The printing press in the 15th century standardized these marks, making punctuation a universal feature of written English. However, differences persist between British and American English, such as the placement of punctuation with quotation marks, which will be explored in later chapters.

Punctuation also adapts to new forms of communication. In digital writing—emails, social media, and text messages—punctuation takes on new roles. For example, multiple exclamation points (!!!) or ellipses (…) in a text message can convey excitement or hesitation, respectively, in ways that traditional writing might not. Emojis, while not traditional punctuation, often serve a similar function, adding emotional cues to digital text. These evolving norms highlight punctuation’s flexibility and its ability to remain relevant in a changing world.

Why Mastering Punctuation Matters

Mastering punctuation is essential for anyone who writes, whether they’re crafting a novel, a business email, or a social media post. Punctuation empowers writers to communicate with precision, ensuring that their ideas are understood exactly as intended. It enhances readability by creating a natural flow that guides readers through the text. And it allows writers to express their unique voice, infusing their work with personality and emotion.

For students, punctuation is a critical skill for academic success. Essays, research papers, and exams require clear, well-structured writing, and proper punctuation is a key component of that clarity. For professionals, punctuation can make the difference between a polished report and a confusing one, impacting credibility and effectiveness. Even in casual settings, such as social media or personal correspondence, punctuation shapes how others perceive the writer’s intelligence and attention to detail.

Chapter 2: The Sentence and Its Structure

The sentence is the cornerstone of written and spoken communication, a self-contained unit of meaning that conveys ideas, emotions, and information. To master punctuation, one must first understand the anatomy of a sentence—its components, structure, and types—and how punctuation interacts with these elements to ensure clarity and coherence. This chapter explores the essential building blocks of a sentence: the subject, predicate, and clauses. It also examines the four primary sentence types—declarative, interrogative, exclamatory, and imperative—and explains how punctuation shapes their function and tone. By grasping these fundamentals, writers can use punctuation strategically to enhance the structure and impact of their sentences, making their writing more precise, engaging, and effective.

Understanding the Sentence: A Definition

A sentence is a group of words that expresses a complete thought and can stand alone as a unit of meaning. At its core, a sentence typically consists of a subject (what or whom the sentence is about) and a predicate (what the subject does or is). Together, these components create a grammatical structure that communicates an idea clearly. For example:

- The dog barked.

In this sentence, “the dog” is the subject, identifying what the sentence is about, and “barked” is the predicate, describing the action of the subject. This simple structure forms the foundation of most sentences, but sentences can vary widely in complexity, incorporating multiple clauses, phrases, and punctuation marks to convey nuanced ideas.

Punctuation is the glue that holds a sentence together, ensuring that its components are organized and its meaning is unambiguous. Without punctuation, even a grammatically correct sentence can become confusing or lose its intended effect. For instance:

- The dog barked the cat ran.

This run-on sentence lacks punctuation to separate the two ideas, making it unclear where one thought ends and another begins. Adding punctuation clarifies the structure:

- The dog barked. The cat ran.

The period separates the two independent clauses, allowing each to stand as a complete sentence. This example highlights punctuation’s critical role in defining sentence boundaries and maintaining coherence, a theme we’ll explore throughout this chapter.

The Subject: The Heart of the Sentence

The subject of a sentence is the person, place, thing, or idea that the sentence is about. It answers the question “Who or what is performing the action or being described?” The subject can be a single word, a phrase, or even a clause, depending on the sentence’s complexity. Let’s examine different types of subjects:

1. Simple Subject: A single noun or pronoun.

- Example: Maria sings.

- Here, “Maria” is the simple subject, identifying who is performing the action.

2. Compound Subject: Two or more nouns or pronouns joined by a conjunction (e.g., and, or).

- Example: Maria and John sing.

- The compound subject “Maria and John” indicates that two people are performing the action.

3. Complex Subject: A noun phrase or clause that functions as the subject.

- Example: The woman who lives next door sings.

- The subject is the entire phrase “The woman who lives next door,” which includes a relative clause providing additional information.

The subject is essential because it anchors the sentence, giving the reader a clear point of reference. Punctuation often interacts with the subject to clarify its role or add information. For example, commas are used to set off nonessential information about the subject:

- The woman, who lives next door, sings beautifully.

The commas around “who lives next door” indicate that this clause is nonrestrictive (additional but not essential to the sentence’s meaning). Without the commas, the clause becomes restrictive, implying that the information is necessary to identify the subject:

- The woman who lives next door sings beautifully.

Here, the lack of commas suggests that the clause specifies which woman is being discussed. This distinction illustrates how punctuation shapes the subject’s role and the sentence’s meaning.

The Predicate: The Action or State of Being

The predicate describes what the subject does, is, or experiences. It typically includes a verb and may also include objects, complements, or modifiers that complete the sentence’s meaning. Like the subject, the predicate can vary in complexity:

1. Simple Predicate: A single verb or verb phrase.

- Example: The dog barked.

- “Barked” is the simple predicate, describing the subject’s action.

2. Compound Predicate: Two or more verbs or verb phrases sharing the same subject, joined by a conjunction.

- Example: The dog barked and wagged its tail.

- The compound predicate “barked and wagged its tail” describes two actions performed by the dog.

3. Complete Predicate: The verb plus all modifiers, objects, or complements that complete the action or description.

- Example: The dog barked loudly at the stranger.

- The complete predicate “barked loudly at the stranger” includes the verb, an adverb (“loudly”), and a prepositional phrase (“at the stranger”).

Punctuation enhances the predicate by clarifying relationships between its components. For instance, commas can separate elements in a compound predicate for readability:

- The dog barked, wagged its tail, and chased the cat.

The commas make the sequence of actions clear, preventing the predicate from feeling cluttered. Similarly, punctuation like dashes or parentheses can add emphasis or supplementary information to the predicate:

- The dog barked—loudly and persistently—at the stranger.

The dashes emphasize the adverbs, adding drama to the predicate. By working with the predicate, punctuation ensures that the sentence’s action or description is conveyed effectively.

Clauses: The Building Blocks of Sentences

A clause is a group of words containing a subject and a predicate. Clauses are the structural units that make up sentences, and they can be classified as independent or dependent:

1. Independent Clause: A clause that can stand alone as a complete sentence.

- Example: The sun sets slowly.

- This clause expresses a complete thought and requires only a period to function as a sentence.

2. Dependent Clause: A clause that cannot stand alone because it is incomplete or relies on another clause for meaning. Dependent clauses often begin with subordinating conjunctions (e.g., because, although, when) or relative pronouns (e.g., who, which, that).

- Example: Because the sun sets slowly.

- This clause is incomplete and needs an independent clause to form a full sentence: Because the sun sets slowly, the sky turns orange.

Punctuation is crucial for managing clauses, as it indicates their relationships and boundaries. For example, a comma often separates a dependent clause from an independent clause when the dependent clause comes first:

- Although she was tired, Maria finished her homework.

The comma signals the transition from the dependent clause (“Although she was tired”) to the independent clause (“Maria finished her homework”). Without the comma, the sentence could feel abrupt or confusing.

Semicolons and colons also play roles in connecting clauses. A semicolon links two independent clauses that are closely related:

- The sun sets slowly; the sky turns orange.

The semicolon creates a smooth connection, emphasizing the relationship between the clauses. A colon, on the other hand, introduces an independent clause that explains or elaborates on the first:

- The sun sets slowly: the sky turns orange.

The colon signals that the second clause provides a result or description of the first. These punctuation choices allow writers to control how clauses interact, shaping the sentence’s structure and meaning.

Sentence Types: The Four Categories

Sentences can be categorized into four types based on their purpose and tone: declarative, interrogative, exclamatory, and imperative. Each type serves a distinct function, and punctuation is essential for signaling that function to the reader.

1. Declarative Sentences: These sentences convey information or state facts and are the most common sentence type. They typically end with a period.

- Example: The sky is blue.

- The period signals the sentence’s informative purpose and conclusive tone.

Declarative sentences can vary in complexity, from simple to compound or complex structures. Punctuation like commas, semicolons, or colons may be used to organize multiple clauses or phrases:

- The sky is blue, and the clouds are fluffy.

- The sky is blue; the clouds are fluffy.

- The sky is blue: a perfect day for a picnic.

Each punctuation mark shapes the sentence’s flow and emphasis, reinforcing its declarative nature.

2. Interrogative Sentences: These sentences ask questions and typically end with a question mark.

- Example: Is the sky blue?

- The question mark indicates the sentence’s inquisitive purpose and prompts a response.

Interrogative sentences may include dependent clauses or phrases, requiring additional punctuation:

- When the sun sets, is the sky blue?

The comma separates the dependent clause (“When the sun sets”) from the main question, ensuring clarity. Question marks are exclusive to interrogative sentences, making them a critical punctuation tool for signaling inquiry.

3. Exclamatory Sentences: These sentences express strong emotion or emphasis and end with an exclamation point.

- Example: The sky is so blue!

- The exclamation point conveys excitement or surprise, amplifying the sentence’s emotional impact.

Exclamatory sentences often use commas or dashes to enhance their dramatic effect:

- The sky, so vibrant and clear, is absolutely stunning!

The commas set off the descriptive phrase, building anticipation for the exclamation. Writers must use exclamatory sentences sparingly to avoid diluting their impact.

4. Imperative Sentences: These sentences give commands, instructions, or requests and typically end with a period, though an exclamation point can be used for emphasis.

- Examples:

- Look at the sky. (Period for a calm command)

- Look at the sky! (Exclamation point for urgency)

Imperative sentences often omit the subject, implying “you” as the doer of the action. Punctuation clarifies the tone and urgency of the command:

- Please, close the door quietly.

The comma after “please” softens the request, making it polite. Understanding the tone of imperative sentences helps writers choose the appropriate punctuation.

Punctuation’s Relevance to Sentence Structure

Punctuation is the framework that supports sentence structure, ensuring that subjects, predicates, clauses, and sentence types work together seamlessly. Each punctuation mark serves a specific purpose in relation to the sentence’s components:

- Periods define sentence boundaries, allowing each complete thought to stand alone. They are essential for declarative and imperative sentences, providing closure and clarity.

- Commas separate elements within a sentence, such as clauses, phrases, or items in a list. They guide the reader through complex structures, preventing confusion.

- Semicolons connect related independent clauses, creating a balance between separation and cohesion.

- Colons introduce explanations, lists, or elaborations, directing the reader’s attention to what follows.

- Question Marks and Exclamation Points signal the sentence’s purpose (inquiry or emphasis) and shape its tone.

Punctuation also interacts with sentence types to reinforce their function. For example, a declarative sentence with multiple clauses may require commas or semicolons to maintain clarity:

- The team practiced daily, improved their skills, and won the championship.

In contrast, an interrogative sentence may use commas to separate introductory elements:

- After practicing daily, did the team win the championship?

By aligning punctuation with sentence structure, writers can ensure that their ideas are presented logically and effectively.

Complex Sentences and Punctuation

As sentences grow more complex, punctuation becomes even more critical. Complex sentences, which contain at least one independent clause and one dependent clause, rely on punctuation to clarify relationships between ideas. Consider this example:

- Because it was raining, we stayed indoors and watched a movie.

The comma after “raining” separates the dependent clause from the independent clause, making the sentence’s structure clear. Without the comma, the sentence is still grammatically correct, but the pause enhances readability.

Compound-complex sentences, which combine multiple independent and dependent clauses, require careful punctuation to avoid confusion:

- Although it was raining, we wanted to go hiking, but we stayed indoors and watched a movie.

Here, commas separate the dependent clause (“Although it was raining”) and the coordinate clauses (“we wanted to go hiking” and “we stayed indoors”), while “and” connects the final clause. This punctuation ensures that the reader can follow the sentence’s layered structure.

Punctuation also helps manage nonrestrictive and restrictive clauses, which provide additional or essential information, respectively:

- My brother, who lives in New York, is visiting. (Nonrestrictive, uses commas)

- My brother who lives in New York is visiting. (Restrictive, no commas)

The presence or absence of commas changes the sentence’s meaning, highlighting punctuation’s role in precision.

Punctuation and Sentence Variety

Effective writing relies on sentence variety—mixing simple, compound, complex, and compound-complex sentences to create rhythm and engagement. Punctuation facilitates this variety by allowing writers to construct sentences of different lengths and structures. For example:

- Simple Sentence: The cat sleeps. (Period for closure)

- Compound Sentence: The cat sleeps, and the dog barks. (Comma and conjunction for connection)

- Complex Sentence: When the cat sleeps, the dog barks. (Comma for clause separation)

- Compound-Complex Sentence: When the cat sleeps, the dog barks, but the bird sings loudly. (Commas for clause separation and coordination)

By varying punctuation, writers can control the pace and tone of their writing. Short sentences with periods create a brisk, direct rhythm, while longer sentences with commas and semicolons slow the pace, allowing for reflection or complexity. This interplay between sentence structure and punctuation is key to crafting dynamic prose.

Common Punctuation Pitfalls in Sentence Structure

While punctuation enhances sentence structure, misuse can lead to confusion or errors. Here are some common pitfalls and how to avoid them:

1. Run-On Sentences: These occur when two independent clauses are joined without proper punctuation or conjunctions.

- Incorrect: The sun sets the sky turns orange.

- Correct: The sun sets. The sky turns orange. (Period)

- Correct: The sun sets, and the sky turns orange. (Comma and conjunction)

2. Comma Splices: These happen when two independent clauses are joined by a comma alone.

- Incorrect: The sun sets, the sky turns orange.

- Correct: The sun sets; the sky turns orange. (Semicolon)

- Correct: The sun sets, and the sky turns orange. (Comma and conjunction)

3. Misplaced Commas: Using commas incorrectly can disrupt sentence structure or change meaning.

- Incorrect: The dog, barked loudly, at the stranger.

- Correct: The dog barked loudly at the stranger.

4. Overusing Punctuation: Excessive punctuation, such as too many commas or exclamation points, can clutter a sentence and weaken its impact.

- Incorrect: The sky, is, so, blue!!!

- Correct: The sky is so blue!

By understanding sentence structure and punctuation rules, writers can avoid these errors and create polished, professional text.

Punctuation’s Role in Different Contexts

The relevance of punctuation to sentence structure varies by context. In academic writing, precise punctuation is essential for clarity and credibility. For example, a research paper might use semicolons and colons to present complex arguments:

- The study revealed two findings: participants preferred option A; however, option B was more cost-effective.

In creative writing, punctuation can enhance style and tone, creating vivid imagery or dialogue:

- The wind howled, the trees swayed, and the storm—wild and unstoppable—descended.

In digital communication, such as emails or social media, punctuation may be more flexible but still plays a role in clarity and tone:

- Can you meet me at 5? (Professional tone)

- OMG, you won’t believe this!!! (Casual, excited tone)
