What this lesson covers
When you're arguing a point in an essay, the way you write matters as much as what you say. A formal style signals to your reader that you take your argument seriously and have thought it through carefully. Formal writing doesn't mean stiff or boring — it means replacing casual language, conversational shortcuts, and emotional outbursts with precise, controlled wording that makes your argument more convincing. In this lesson, you'll learn how to identify informal elements in your writing and replace them with formal alternatives that maintain the strength and clarity of your ideas.
What Formal Style Means in Argument
Formal style in argumentative writing is the careful, measured tone you use when addressing an audience who expects professional communication. It isn't about using big words or sounding like a textbook. Instead, formal style means making deliberate choices: avoiding slang, removing conversational shortcuts, and steering clear of language that reveals emotion rather than reasoning. When you maintain formal style, your reader focuses on the logic of your claim, not on your mood or personality. Think of it this way — if you were presenting your argument to a school board or a newspaper editor, you wouldn't say things like "it's crazy" or "you totally know that's wrong." You'd say something like "the evidence contradicts this position" or "this interpretation does not account for available data." Formal style earns respect for your ideas.
Replacing Slang and Casual Language
Slang and casual expressions belong in conversation with friends, but they weaken an argument in writing. Words like "got," "a lot," "basically," "literally" (when used loosely), and "pretty much" are signals that you're not being precise. In formal argument, precision matters. Instead of saying "this is a bad idea," identify what makes it problematic: "this approach overlooks environmental costs" or "this method lacks scientific support." Instead of "everyone agrees it's true," write "research demonstrates" or "evidence supports." Slang isn't just about trendy words — it's about imprecise, vague language that tells rather than shows. When you remove slang, you're often forced to be more specific, which actually strengthens your argument. Your reader can then evaluate the real substance of what you're saying instead of getting distracted by informal phrasing.
Eliminating Contractions and Second-Person "You"
Contractions like "don't," "it's," "won't," and "can't" are shortcuts that belong in speech and informal writing. In formal argument, spell them out: "do not," "it is," "will not," "cannot." Writing out the full form slows the reader's eye slightly and gives weight to each word — an effect that serves argument well. Similarly, avoid second-person "you" in explanatory prose. Saying "you know that pollution harms the environment" is conversational, but it puts the reader on the spot and can feel accusatory. Instead, write "pollution harms the environment" or "evidence shows that pollution harms the environment." This shift keeps focus on the claim itself, not on your relationship with the reader. When addressing the reader becomes necessary — for instance, in a conclusion about action — use third-person or passive constructions: "citizens should" or "individuals must" rather than "you should."
Managing Exclamation and Emotional Overstatement
Exclamation marks in argument writing signal that you're relying on emotion rather than evidence. "This policy is absolutely outrageous!" tells the reader how to feel, but it doesn't make the argument stronger. Replace exclamation with precise, measured language: "this policy contradicts the stated goals of the program" or "this approach creates unintended consequences." Emotional overstatement — words like "always," "never," "obviously," "clearly," and hyperbolic descriptions — does the same thing. These words claim certainty you usually don't have and often make readers skeptical. Instead, use measured language: "frequently," "often," "in many cases," "evidence suggests," "research indicates." When you remove the emotional charge, your reasoning becomes the focus. A reader who might dismiss an angry claim will seriously consider a calm, well-supported one. Formal style doesn't mean your argument loses force — it means the force comes from logic and evidence, not from tone.
Keeping Meaning and Force While Shifting Register
The biggest worry students have is that making language formal will make their argument weaker or less interesting. That's actually backwards. When you move from "this is totally unfair!" to "this decision contradicts the school's stated commitment to equity," you've kept the punch but made it land harder. The meaning stays the same — you're still saying something is wrong — but now the reader can engage with your reasoning instead of dismissing you as emotional. Formal style is a tool for making your strongest argument. It's not about stuffing your writing with fancy words or removing personality. It's about choosing words that do the work of argument: words that define, compare, qualify, and explain. When you write formally, you signal that you respect the complexity of the issue and expect your reader to think carefully about it. That respect is persuasive.
Key terms
- Formal style.
- A register of writing that is precise, measured, and appropriate for an educated audience; it avoids slang, contractions, conversational shortcuts, and emotional language in favor of exact, controlled wording.
- Contraction.
- A shortened form of a word or pair of words made by omitting letters and usually adding an apostrophe, such as 'don't' for 'do not' or 'it's' for 'it is'; contractions are informal and are avoided in formal argument writing.
- Register.
- The level of formality or style in language, determined by audience, purpose, and context; moving between registers means adjusting how you write for different situations.
- Emotional overstatement.
- Language that exaggerates the strength of a claim or relies on feelings rather than evidence, such as 'absolutely always' or 'completely outrageous'; it weakens argument by signaling the writer cannot support the claim with logic alone.
- Slang.
- Very informal language and expressions that are common in casual speech but are inappropriate in formal writing; slang is often imprecise and audience-specific.
- Measured language.
- Wording that is careful, qualified, and avoids absolute claims; it uses phrases like 'often,' 'frequently,' 'may indicate,' and 'suggests' to express ideas accurately without overstatement.
- Second-person pronoun.
- The pronoun 'you' and related forms, which directly address the reader; in formal argument, second-person is avoided in explanatory prose because it can sound conversational or accusatory.
Worked example
Rewrite the following informal argument in a formal style, keeping the same meaning and point: "Honestly, you guys gotta see that extending school days is totally terrible! It's gonna make students way too tired, and obviously, nobody can focus when they're exhausted. You can't expect kids to learn anything when they're falling asleep in class!"
Let's work through this step by step. First, identify all the informal elements: 'Honestly,' 'you guys gotta,' 'totally terrible,' 'gonna,' 'way too,' 'obviously,' 'nobody,' and 'can't' (contraction), plus the exclamation marks and second-person 'you.' Start by removing the conversational opener and establishing a clear claim. Replace "you guys gotta see that extending school days is totally terrible" with a formal thesis: "Extending school days would negatively affect student learning outcomes." Now replace the emotional language and contractions. Instead of "It's gonna make students way too tired," write "Extended instructional time would increase student fatigue." Replace the emotional overstatement "obviously, nobody can focus" with measured, evidence-based language: "Research indicates that fatigue impairs concentration and academic performance." Finally, replace the accusatory second-person construction "You can't expect kids to learn" with "Students cannot retain information effectively" or "Learning cannot occur when students are exhausted." Here's the formal version: "Extending school days would negatively affect student learning outcomes. Extended instructional time would increase student fatigue, which research indicates impairs concentration and academic performance. Students cannot retain information effectively when exhausted, making longer school days counterproductive to educational goals." Notice that the argument is stronger now — the same point is made, but without the emotion, readers can focus on the actual reasoning.
Practice questions
Which sentence is written in a formal style appropriate for an argument essay?
- Students can't handle the pressure of too much homework, and it's honestly way too much.
- Excessive homework creates stress that negatively affects student well-being and academic performance.
- You guys obviously know that teachers give out way too much homework these days!
- Homework is really bad, and students are totally struggling because of it.
Answer: Excessive homework creates stress that negatively affects student well-being and academic performance.
This sentence uses precise, measured language ('creates,' 'negatively affects') and avoids contractions, slang, emotional overstatement, and second-person address. The other options contain contractions ('can't,' 'it's'), casual expressions ('way too much,' 'you guys,' 'obviously,' 'totally'), and exclamation, all of which belong to informal style. Formal style doesn't mean the argument is weak — it means the argument's force comes from reasoning and word choice, not emotion.
Rewrite this informal sentence in a formal style: "You definitely can't argue that social media isn't ruining teenagers' mental health — it's obvious!" Explain what changes you made and why they strengthen the argument.
Answer: Research indicates that excessive social media use correlates with increased rates of anxiety and depression among adolescents. Changes made: removed second-person 'you,' replaced the contraction 'can't' with 'cannot,' removed the emotional opener 'definitely' and the exclamation mark, replaced 'ruining' (vague and emotional) with 'correlates with increased rates of' (precise and evidence-based), and replaced 'it's obvious' with 'research indicates' (measured and source-grounded). These changes strengthen the argument because they move the reader's focus from the writer's emotional certainty to the actual evidence and logic supporting the claim. Instead of demanding agreement, the formal version invites the reader to consider the reasoning.
Formal style shifts the register from conversational conviction to logical argumentation. When you remove the emotion and replace it with precise language and qualified claims, readers take the argument more seriously because it appeals to reason rather than feeling. Saying 'research indicates' is more credible than saying 'it's obvious' because it acknowledges that the claim is based on evidence, not just opinion.
Which of these is a contraction, and why should it be eliminated in formal argumentative writing?
- definitely
- analyze
- won't
- complex
Answer: won't
A contraction is a shortened form of two words with letters omitted and an apostrophe added. 'Won't' is the contraction of 'will not.' In formal argumentative writing, contractions should be eliminated because they are conversational shortcuts that reduce the weight and precision of formal prose. Writing 'will not' instead of 'won't' slows the reader slightly and signals that the writing is careful and measured. The other words are not contractions: 'definitely' is an adverb, 'analyze' is a verb, and 'complex' is an adjective.
FAQ
- If I use formal style, will my argument sound cold or boring?
- No. Formal style means precise, measured language — not stiff or dull writing. In fact, when you remove emotional language and replace vague words with exact ones, your argument becomes more interesting because readers can focus on your reasoning. 'Students perform worse on tests after poor sleep' is more compelling than 'students are so tired they can't even think,' because the first one sounds like you've actually thought about the problem and have evidence for it. Formal style earns respect.
- Can I ever use 'you' in a formal argument essay?
- In explanatory and evidence sections, avoid second-person 'you.' However, in a conclusion where you're calling readers to action or addressing them directly about implications, second-person can work if it's genuinely necessary. Most of the time, though, you can rewrite 'you should consider' as 'individuals should consider' or 'the audience should consider.' Stick with third-person or passive constructions in the body of your argument.
- What's the difference between formal style and sounding fake or pretentious?
- Formal style uses precise, accurate language that fits the situation. Sounding pretentious means using words you don't understand or that don't fit naturally. Use words you know and that express your meaning exactly. 'The policy is ineffective' is formal. 'The policy demonstrates a lamentable deficiency in infrastructural paradigmatization' (if you don't actually mean that) is pretentious and confusing. Formal means clear, not complicated.
- If I remove all exclamation marks and emotional language, how do I show my argument is important or passionate?
- The importance and power of your argument should come from your evidence and reasoning, not from punctuation or tone. When you support a claim with solid evidence and logical explanation, readers feel the weight of your point without you having to shout about it. An argument built on research and careful reasoning is far more powerful than an emotional one. Your passion shows in how thoroughly you've researched and thought through your position.
