Then vs Than: What’s the Difference? (10 Examples + Easy Trick)

Then and than sound almost identical, but swapping them changes the meaning of a sentence — and it is one of the most common grammar mistakes in English, even for native speakers. The good news is that the rule is simple, and once you learn one easy trick, you will never confuse them again.

Here is the whole rule in one line: then is for time, than is for comparison. That is it. The rest of this guide shows you how to apply it with examples, a memory trick, and the tricky cases that trip people up.

Quick Rule: Then Is for Time, Than Is for Comparison

If your sentence is about when something happens, what happens next, or what happens as a result, use then. If your sentence compares two things, people, or amounts, use than.

A fast test works every time. Replace the word with “after that” or “next” — if the sentence still makes sense, you need then. Replace it with “compared to” — if that fits, you need than.

What Does “Then” Mean? (Definition + 5 Sentence Examples)

Then is an adverb that points to time, sequence, or consequence. It can mean “at that time,” “next,” or “as a result.”

1. “We finished dinner, then we went for a walk.”
2. “First, wash your hands, then eat.”
3. “If you finish your homework, then you can watch a movie.”
4. “Back then, phones did not have cameras.”
5. “She studied hard, and then she passed the exam.”

Notice the pattern in every example: something happens, and then something else follows — in time, in order, or as a result. That is the job of “then,” and it never compares anything.

What Does “Than” Mean? (Definition + 5 Sentence Examples)

Than is a conjunction (sometimes a preposition) that introduces the second part of a comparison. It always follows a comparative word like more, less, better, bigger, or rather.

1. “She is taller than her brother.”
2. “This book is better than the last one.”
3. “I would rather walk than drive.”
4. “He spent less than he planned.”
5. “Today is colder than yesterday.”

The Cambridge Dictionary defines “than” as a word used to join two parts of a comparison — see the Cambridge Dictionary definition of than.

In every example, two things are being measured against each other. If there is no comparison, there is no “than.”

The A/E Trick: How to Never Confuse Them Again

Here is the easiest memory trick for then vs than, and it works because of the vowels.

ThAn = compArison. Both “than” and “comparison” contain the letter A.

ThEn = whEn / nExt. Both “then” and “when” (and “next”) contain the letter E.

So when you are stuck, look at the vowel. Thinking about a comparison? You want the A word: than. Thinking about when something happens? You want the E word: then. Students who learn this trick rarely mix them up again, because it turns a grammar rule into a one-second spelling check.

10 Common Mistakes With Then and Than (Wrong → Right)

These are the mistakes that show up most often in essays, emails, and social media posts. Each one is fixed with the quick rule above.

1. Wrong: “She is smarter then me.” → Right: “She is smarter than me.”
2. Wrong: “Finish your work, than you can play.” → Right: “Finish your work, then you can play.”
3. Wrong: “I like tea more then coffee.” → Right: “I like tea more than coffee.”
4. Wrong: “We went home, than we slept.” → Right: “We went home, then we slept.”
5. Wrong: “He is older then his sister.” → Right: “He is older than his sister.”

6. Wrong: “If you call, than I will answer.” → Right: “If you call, then I will answer.”
7. Wrong: “This is better then expected.” → Right: “This is better than expected.”
8. Wrong: “Back than, life was simpler.” → Right: “Back then, life was simpler.”
9. Wrong: “Rather then stay, he left.” → Right: “Rather than stay, he left.”
10. Wrong: “First study, than relax.” → Right: “First study, then relax.”

Read each corrected sentence out loud once, and the pattern starts to feel automatic: comparisons take “than,” everything about order takes “then.”

Tricky Cases: “Than Me or Than I?” / “Different Than or Different From?”

Two cases confuse even confident writers, so let us settle them.

“Than me” or “than I”? In everyday speech, “than me” is normal and accepted: “She is taller than me.” In formal writing, “than I” is used when a verb is understood: “She is taller than I (am).” Both are correct in their place — use “than me” in casual writing and “than I” in formal essays.

“Different than” or “different from”? Traditional grammar prefers “different from”: “This is different from the last one.” “Different than” is common in American English, especially before a clause: “The result was different than we expected.” If you want to be safe in exams and formal writing, choose “different from.”

One more trap: “more then” is never correct when you mean “more than.” The word after “more” is almost always “than,” because “more” is a comparison word.

Frequently Asked Questions About Then and Than

What is the difference between then and than?

Then is about time, sequence, or result. Than is about comparison. “We ate, then we left” uses then; “bigger than mine” uses than.

How can I remember then vs than easily?

Use the A/E trick: thAn = compArison (both have A), thEn = whEn (both have E). That one check solves almost every case.

Is “more then” ever correct?

No, not when you mean a comparison. “More” is a comparison word, so it is followed by “than”: “more than enough.”

Is it “than me” or “than I”?

Both are correct in different settings. “Than me” is standard in casual speech, while “than I” fits formal writing where a verb is understood.

Is “different than” wrong?

It is not wrong in American English, but “different from” is the safer, more traditional choice in formal writing and exams.

Can then and than ever be swapped?

No. Swapping them changes the meaning or makes the sentence wrong, because one marks time and the other marks comparison.

What comes after “rather” — then or than?

Than. “Rather” expresses preference, which is a comparison: “I would rather stay than go.”

Conclusion

Then vs than becomes easy once you stop memorizing and start testing. Ask one question: am I talking about time, or am I comparing? Time and order take “then,” comparisons take “than,” and the A/E trick — thAn for compArison, thEn for whEn — catches you whenever you hesitate.
