You're staring at two sentences. The other sounds like a legal contract. One sounds like a text to your best friend. You know there's a difference — but when someone asks you to point to the formal one, your brain freezes.
Happens more than you'd think.
The phrase "which sentence is an example of formal language" gets searched thousands of times a month. Which means not because people don't understand the concept. Which means because the line between "professional" and "stiff" gets blurry fast. And most examples online are either painfully obvious or so academic they're useless in real life.
Let's fix that.
What Is Formal Language
Formal language isn't about using big words to sound smart. It's about precision, objectivity, and distance. You're not trying to impress anyone. You're trying to be unambiguous.
Think of it this way: formal language removes the speaker. No "I think," no "you know," no "honestly." The writing stands on its own Most people skip this — try not to. Less friction, more output..
The markers are consistent
- Complete sentences. Always. No fragments for effect.
- No contractions. "Cannot" instead of "can't." "Will not" instead of "won't."
- Third-person perspective. Even when you're the one writing.
- Precise vocabulary. "Investigate" not "look into." "Establish" not "set up."
- Passive voice appears more often — not because it's better, but because the actor often doesn't matter.
It's not the same as "academic" or "legal"
This trips people up. Academic writing uses formal language, but adds citation conventions, hedging ("suggests," "indicates"), and discipline-specific jargon. Legal writing takes formal language and weaponizes it — every word has been litigated.
Business formal sits somewhere in the middle. Polished, direct, but still human enough to read without a law degree.
Why It Matters / Why People Care
You've sent an email that came off wrong. We all have.
Maybe you wrote "Hey, just wanted to touch base real quick" to a VP you've never met. Or you submitted a cover letter that said "I'm super passionate about this role" and wondered why you didn't get a callback Easy to understand, harder to ignore..
Formal language signals context awareness. It tells the reader: I understand where I am, who you are, and what this situation requires.
The stakes are real
In hiring, a too-casual tone reads as immature. In client work, it reads as unprofessional. In academic or government contexts, it reads as unqualified.
But here's what most guides miss: overly formal language backfires too.
"I hereby wish to express my sincere gratitude for your consideration of my application" doesn't sound professional. It sounds like a bot wrote it. Or someone trying too hard Less friction, more output..
The sweet spot is appropriate formality. Not maximum formality.
How to Identify Formal Language in a Sentence
This is the practical part. When you're looking at two sentences and need to pick the formal one, run through this checklist.
1. Check for contractions
Informal: "The team can't meet the deadline." Formal: "The team cannot meet the deadline."
Simple. Reliable. Works 95% of the time.
2. Look at the pronouns
Informal: "You should review the proposal before Friday."
Formal: "The proposal should be reviewed before Friday."
Also formal: "Review of the proposal is required before Friday.
First and second person (I, we, you) signal informality. Third person or passive construction signals formality.
3. Spot the phrasal verbs
Phrasal verbs — verb + preposition combos — are the heartbeat of spoken English. Formal writing replaces them with single Latinate verbs That's the whole idea..
| Informal (Phrasal) | Formal (Single Verb) |
|---|---|
| find out | determine |
| go over | review |
| put off | postpone |
| come up with | generate |
| look into | investigate |
| point out | indicate |
If a sentence uses "find out," it's almost certainly informal. "Determine" flips the switch That's the part that actually makes a difference..
4. Evaluate the vocabulary precision
Informal: "The results were pretty good." Formal: "The results were favorable."
Informal: "This is a big problem." Formal: "This presents a significant challenge."
Formal language avoids vague intensifiers (very, really, pretty, kind of) and opts for specific descriptors Nothing fancy..
5. Sentence structure and length
Informal sentences tend to be shorter, choppier, more conversational. Formal sentences often use subordination — dependent clauses, relative clauses, appositives — to pack in relationships between ideas.
Informal: "The project failed. The budget was too small.Still, we didn't have enough time. " Formal: "The project failed due to insufficient time and budgetary constraints.
Same facts. Different architecture.
Real Examples Side by Side
Let's look at actual pairs. The kind you'd see on a test — or in a real email thread It's one of those things that adds up. Surprisingly effective..
Example 1: Workplace communication
A. "Hey team, just a heads up — we're gonna need those reports by EOD Thursday. Let me know if that's an issue!"
B. "Please be advised that all reports are due by end of day Thursday. Kindly notify your supervisor if this timeline presents a conflict."
Sentence B is formal. Polite but distant ("kindly notify"). Passive construction ("are due"). On the flip side, no contractions. "Presents a conflict" instead of "that's an issue.
Example 2: Academic context
A. "The study shows that sleep deprivation messes with your memory."
B. "The study demonstrates that sleep deprivation impairs memory function."
"Shows" → "demonstrates." "Messes with" → "impairs.Which means " "Your memory" → "memory function. " Every swap increases precision and distance.
Example 3: Customer service
A. "Sorry about the wait! We're working on it and'll get back to you soon."
B. "We apologize for the delay. Our team is addressing the issue and will respond promptly."
"We're" → "we are.Also, " "And'll" (double contraction! Day to day, ) → "and will. " "Soon" → "promptly." "Sorry" → "apologize.
Example 4: The trick question
A. "It is imperative that we ascertain the veracity of the aforementioned assertions."
B. "We must verify the claims."
Here's the trap. Sentence A looks more formal. Bigger words. In practice, more syllables. But it's performative — formal cosplay. Sentence B is actually better formal writing: precise, direct, no wasted words.
True formal language values clarity over complexity. Always.
Common Mistakes / What Most People Get Wrong
Mistake 1: Confusing "formal" with "flowery"
"I am writing to inform you that..." — stop. Just start with the information. That's why "The meeting is rescheduled to Friday" is more formal than "I am writing to inform you that the meeting has been rescheduled to Friday. " Fewer words. More authority.
Mistake 2: Thinking passive voice
is always better.
While the passive voice ("The decision was made") is a staple of formal writing because it removes personal bias, overusing it can make your writing feel sluggish and evasive. Use the passive voice when the action is more important than the actor, but don't use it just to hide behind a curtain of ambiguity.
Mistake 3: Overusing "nominalizations"
A nominalization is a verb or adjective turned into a heavy noun.
- Informal/Weak: "We will analyze the data."
- Pseudo-Formal/Heavy: "We will perform an analysis of the data.
While "perform an analysis" sounds "fancier," it actually adds unnecessary weight to the sentence. If you can use a strong, direct verb, do so Easy to understand, harder to ignore..
Summary Checklist
When you are editing your work to ensure the appropriate level of formality, run through this mental checklist:
- Check your contractions: Have you used don't, can't, or it's? If the context is formal, expand them to do not, cannot, and it is.
- Audit your verbs: Are you using "phrasal verbs" (e.g., set up, find out, look into)? Replace them with single-word alternatives (establish, discover, investigate).
- Evaluate your pronouns: Are you using "you" and "me" too much? In high-level academic or legal writing, shifting toward the third person ("the researcher," "the participant," "the consumer") creates the necessary professional distance.
- Scan for "filler" words: Words like really, very, basically, and actually add nothing to a formal sentence. If a word doesn't add meaning, delete it.
Conclusion
Mastering the distinction between formal and informal language is not about learning a second vocabulary; it is about learning to adjust your "social distance" through text.
Informal language is the language of connection—it is warm, fast, and builds rapport. Even so, it is perfect for a text message to a friend or a Slack message to a close colleague. Formal language is the language of authority, precision, and objectivity. It is designed to minimize personal bias and maximize clarity in professional, legal, and academic spheres.
The goal is not to always write formally. The goal is to always write appropriately. When you understand the tools of tone, you gain the ability to command a room—even when you aren't physically in it Took long enough..
