Understanding the difference between than and then is one of the most common challenges in English grammar, even for confident writers. These two short words look similar and sound almost identical, yet they serve completely different purposes. Mixing them up can change the meaning of a sentence, reduce writing clarity, and make otherwise polished content appear careless. That is why mastering than vs then is essential for anyone who wants to communicate clearly and professionally.
The word than is used for comparison, helping readers understand differences between people, objects, or ideas. In contrast, then relates to time, sequence, or what happens next. Confusing a comparison word with a time-related adverb may seem minor, but it is one of the most noticeable common English mistakes in emails, essays, and online content. Readers often judge language skills based on such errors, especially in academic and professional writing.
By learning the correct grammar rules, recognizing sentence patterns, and reviewing clear examples, you can easily avoid this mistake. This guide breaks down the real difference between than and then, explains why the confusion happens, and shows practical ways to use both words correctly. With a little attention, your sentences will sound more natural, accurate, and confident every time.
Why “Than vs Then” Still Confuses Even Strong Writers
The confusion between than and then isn’t about intelligence. It’s about habit, sound, and speed.
When spoken, than and then sound almost identical in many American accents. In fast speech, the vowel difference nearly disappears. That sound overlap trains the brain to treat them as interchangeable, even though they aren’t.
There’s also the speed problem. Most people type faster than they think. When writing quickly—especially on phones—your brain chooses the familiar pattern instead of the correct one.
A few real reasons this mistake survives:
- Both words are common in everyday language
- Spellcheck doesn’t flag the error
- Predictive text often suggests the wrong option
- People learn the rule once, then forget it
- Social media normalizes incorrect usage
The result is a tiny error that spreads everywhere.
However, here’s the key truth.
Than and then are never interchangeable. Ever.
Once that clicks, everything becomes simpler.
The Core Difference Between Than and Then (One-Sentence Rule)
If you remember only one thing, remember this:
- Than is used for comparisons
- Then is used for time, sequence, or results
That’s it. That rule covers nearly every case.
You compare things with than.
You describe time, order, or consequences with then.
Let’s unpack that properly.
What “Than” Means and How It Works in Real Sentences
Than is a conjunction or preposition used only to compare one thing to another.
If you can replace the word with “in comparison to,” you need than.
Core Function of “Than”
- Shows contrast or comparison
- Connects two unequal elements
- Often follows comparative adjectives or adverbs
Common Comparative Structures with “Than”
- Bigger than
- Faster than
- Smarter than
- More expensive than
- Less important than
Clear Examples
- This phone is cheaper than the other model.
- She runs faster than her teammates.
- Remote work is more flexible than office work.
Each sentence compares two things. That’s why than is correct.
A Common Gray Area: “Different Than”
You may hear debates about phrases like “different than” vs “different from.”
Here’s the reality in modern American English:
- Different from is traditionally preferred
- Different than is widely used and accepted in informal contexts
In formal writing, especially academic or professional work, different from remains the safer choice.
What “Then” Really Means (It’s More Than Just Time)
Then relates to when something happens, what comes next, or what follows as a result.
Think of then as a timeline word.
The Three Core Uses of “Then”
Time Reference
- Back then, things were simpler.
- We lived in New York then.
Sequence or Order
- Finish your work, then submit the form.
- First read the instructions, then begin.
Cause and Effect
- If you skip practice, then you’ll struggle.
- Study consistently, then results follow.
In logic and conditional statements, then acts as a connector between cause and outcome.
Than vs Then: Side-by-Side Comparison Table
| Feature | Than | Then |
| Primary function | Comparison | Time, sequence, result |
| Answers the question | “Compared to what?” | “When?” or “What next?” |
| Common partners | More, less, better, worse | If, first, next, after |
| Part of speech | Conjunction / preposition | Adverb |
| Example | Taller than me | Eat first, then leave |
This table alone clears up most confusion. When in doubt, check which column your sentence belongs in.
Mistakes Native Speakers Make All the Time
Even fluent speakers slip up. Not because they don’t know better, but because writing habits form early and stick.
Common Real-World Errors
- “She’s better then me” ❌
- “More then enough” ❌
- “I’d rather stay home then go out” ❌
All of these are comparisons. They require than, not then.
Why does this happen so often?
- Fast typing
- Overreliance on autocorrect
- Informal digital writing habits
- Sound-based spelling
Once an error becomes familiar, the brain stops questioning it.
How Mixing Up Than vs Then Changes Meaning
Sometimes the mistake looks harmless. Other times, it breaks logic completely.
Example Breakdown
- Correct: I’d rather read than watch TV.
- Incorrect: I’d rather read then watch TV.
The incorrect version suggests a sequence, not a preference. The meaning collapses.
In professional writing, these errors can:
- Confuse readers
- Reduce trust
- Signal weak language control
- Hurt academic or exam performance
