Than vs Then: What Is the Difference & Which Is Correct?

“Than” and “then” look and sound similar, but they have completely different meanings and grammatical functions. Than is mainly used for comparisons, while then usually refers to time, sequence, or a result. Understanding this small but important difference can help you avoid common spelling and grammar mistakes in emails, essays, conversations, and everyday writing.

Comparison Overview

Than and then are two commonly confused English words. Their similar spelling often causes writers and speakers to mix them up, but they serve different purposes.

Than is primarily used when comparing two or more people, things, actions, qualities, or amounts.

• My car is faster than yours.
• She is taller than her sister.
• This book is more interesting than the last one.

Then, on the other hand, commonly relates to time, order, sequence, or consequence.

• We finished dinner and then watched a movie.
• I lived in London then.
• If you study hard, then you can pass the exam.

A simple way to remember the distinction is:

Than = comparison
Then = time, sequence, or result

Word	Main Function	Meaning	Example
Than	Comparison	Used to compare things	She is older than me.
Then	Time/sequence	At that time or next	We ate, then left.
Then	Result	In that case	If you’re ready, then let’s begin.

Definition of Than

Than is a conjunction or preposition commonly used to introduce the second part of a comparison.

It appears after comparative words such as:

• better
• worse
• bigger
• smaller
• faster
• slower
• older
• younger
• more
• less
• fewer

For example:

• This laptop is cheaper than that one.
• Maria runs faster than I do.
• I have more work than yesterday.
• He is less nervous than before.

The main purpose of than is to show a difference or comparison between two things.

Than in Comparisons

The most common structure is:

comparative adjective/adverb + than + person or thing

Examples:

• This test is easier than the previous one.
• Ali speaks more clearly than his brother.
• Summer is hotter than spring.

You can also use than after nouns and pronouns in comparisons:

• I have more books than you.
• She has fewer problems than I do.
• They spent more money than we expected.

Is Than a Verb or Noun?

No. Than is not normally used as a verb or noun. It functions mainly as a conjunction or preposition in comparisons.

For example:

• Correct: She is taller than me.
• Correct: She is taller than I am.

The word connects the two parts of the comparison.

Definition of Then

Then is an adverb with several related meanings. It commonly refers to a particular time, the next event in a sequence, or a result that follows from a condition.

Examples:

• I was living in New York then.
• First, wash the vegetables; then cut them.
• If you agree, then we can proceed.

Unlike than, then is not normally used to compare two things.

Then for Time

Then can mean “at that time.”

• I was much younger then.
• She lived in Paris then.
• Things were different then.

It can also refer to a future or expected time:

• Finish your homework, and then you can play.
• We will discuss the budget then.

Then for Sequence

Then is frequently used to show that one action happens after another.

Common pattern:

First → next → then → finally

For example:

• First, open the application.
• Then, enter your password.
• Then, click the login button.
• Finally, select your account.

Then for Results

Then can also introduce a consequence or result, especially after an “if” clause.

• If you’re tired, then take a break.
• If the weather improves, then we will go outside.
• If you finish early, then you can leave.

In these sentences, then has a meaning similar to “in that case.”

Main Differences Between Than and Then

The biggest difference between than and then is their function.

Than compares. Then relates to time, sequence, or consequence.

Feature	Than	Then
Primary purpose	Comparison	Time or sequence
Common meaning	In comparison with	At that time / next
Grammatical role	Conjunction or preposition	Adverb
Used with comparatives?	Yes	No
Used to show sequence?	No	Yes
Used to describe a past time?	No	Yes
Used for conditional results?	No	Yes
Example	Better than before	Finish this then start that

Compare With “Than”

Use than when one thing is being compared with another.

• My phone is newer than yours.
• This route is shorter than the other one.
• She is more experienced than him.

The comparison may involve:

• size
• age
• quality
• quantity
• speed
• cost
• ability
• preference
• performance

Sequence With “Then”

Use then when explaining what happens next.

• We had lunch and then went shopping.
• Read the instructions and then answer the questions.
• She finished her work and then called her manager.

Time With “Then”

Use then to refer to a particular time.

• I didn’t understand it then.
• We were living abroad then.
• Life was very different then.

Conditional Results With “Then”

Use then when showing what will happen as a result of a condition.

• If you need help, then call me.
• If the price is too high, then choose another option.

Why Are Than and Then So Commonly Confused?

The confusion exists mainly because the words are visually and phonetically similar.

They differ by only one letter:

• Than
• Then

However, their meanings are entirely different.

Another reason for confusion is fast writing and typing. People may type then automatically when they mean than, especially in informal messages.

For example:

• Incorrect: My car is faster then yours.
• Correct: My car is faster than yours.

The reverse mistake can also happen:

• Incorrect: First finish your work, than take a break.
• Correct: First finish your work, then take a break.

Common Mistakes Learners Make

Mistake 1: Using “Then” in a Comparison

Incorrect:

• This phone is better then mine.

Correct:

• This phone is better than mine.

Why? Better introduces a comparison, so than is required.

Mistake 2: Using “Than” for Sequence

Incorrect:

• Finish your homework, than go to bed.

Correct:

• Finish your homework, then go to bed.

Why? The sentence describes what happens next, so then is correct.

Mistake 3: Confusing “Then” With “Than” in Questions

Incorrect:

• Which is better, tea then coffee?

Correct:

• Which is better, tea than coffee?

More naturally:

• Which is better, tea or coffee?

When a comparison uses “better,” than is the comparison word, but some sentence structures use or instead.

Mistake 4: Using “Than” for a Past Time

Incorrect:

• I was very young than.

Correct:

• I was very young then.

Here, then means “at that time.”

Simple Rules to Remember

Use these four rules:

1. Than = comparison.
2. Then = time.
3. Then = next in a sequence.
4. Then = result or consequence in some conditional sentences.

A quick memory trick is:

ThAn = compArison

The A in “than” can remind you of “comparison.”

For then, think about time or what happens next.

Quick Tips for Writing and Speaking

When you’re unsure, ask yourself what the sentence is doing.

Is it comparing two things?

Use than.

• He is taller than me.

Is it explaining what happens next?

Use then.

• He ate dinner and then left.

Is it referring to a particular time?

Use then.

• I didn’t know that then.

Is it showing a result after a condition?

Use then.

• If that’s true, then we should investigate.

Reading the entire sentence instead of focusing only on the similar spelling can usually reveal the correct choice.

Final Verdict

Than and then are both correct English words, but they cannot normally be used interchangeably. The key is understanding what you want the sentence to express.

Use than when you are comparing people, objects, actions, qualities, quantities, or ideas. It commonly follows comparative words such as better, worse, faster, slower, more, less, fewer, older, and younger.

Use then when you are talking about time, sequence, or a result. It can mean “at that time,” “next,” or “in that case.”

The easiest rule to remember is:

Than = comparison.
Then = time, sequence, or result.

So, write “My car is faster than yours” but “I ate dinner and then went home.” Once you connect than with comparison and then with time or sequence, this common grammar confusion becomes much easier to avoid.

Conclusion

Understanding Than vs Then becomes much easier when you focus on what each word means and how it functions in a sentence. Than is used mainly for comparisons, especially after words such as better, faster, more, less, and older. Then is used to talk about time, sequence, or a result, such as when describing what happens next or referring to a particular moment.

The simplest rule to remember is “than = comparison” and “then = time or sequence.” For example, you would say, “This book is better than that one,” but “Finish the book and then write a summary.” Keeping this distinction in mind can help you avoid one of the most common English word-choice mistakes. Whether you are writing an email, school assignment, article, or everyday message, choosing than and then correctly will make your writing clearer, more accurate, and more professional.

FAQs

What is the main difference between Than and Then?

Than is primarily used to make comparisons, while then usually refers to time, sequence, or a result. For example, “She is taller than me” compares two people. In contrast, “She finished work and then went home” describes the order of two events. Their similar spelling makes them easy to confuse.

When should I use Than?

Use than when comparing two or more people, objects, qualities, quantities, or actions. It commonly follows comparative words such as better, worse, faster, slower, older, younger, more, and less. For example, “This computer is faster than my old one.” If the sentence expresses a comparison, than is usually the correct choice.

When should I use Then?

Use then when referring to a particular time, describing what happens next, or showing a consequence. For example, “I lived there then” refers to a past time, while “Finish your work and then take a break” shows sequence. In conditional sentences, then can also mean “in that case.”

Is than used for comparisons?

Yes. Than is the standard word used to introduce the second part of many comparisons. You can use it after comparative adjectives, adverbs, and expressions involving quantity. Examples include “better than,” “faster than,” “more expensive than,” and “less difficult than.” Remembering “than = comparison” is an effective way to avoid mistakes.

Is then used for time?

Yes. Then can refer to a specific time, especially a time in the past or a time already mentioned. For example, “I was living in London then” means “I was living in London at that time.” Then can also describe a future point, as in “We can discuss it then.”

Can Than and Then be used interchangeably?

No. Than and then have different meanings and grammatical functions, so they generally cannot replace each other. Use than for comparisons and then for time, sequence, or consequences. Writing “better then” instead of “better than,” for example, changes a grammatically correct comparison into an error.

What is an easy way to remember Than vs Then?

A useful memory trick is “than = comparison” and “then = time or next.” If you are comparing two things, choose than. If you are describing when something happened or what happens afterward, choose then. This simple association works well in both everyday conversation and formal writing.

Which is correct: “better than” or “better then”?

The correct expression is “better than.” The word better is comparative, so it requires than when introducing the thing being compared. For example, “This solution is better than the previous one.” Then would be incorrect because the sentence is making a comparison rather than describing time or sequence.

Which is correct: “first then” or “first than”?

The correct phrase is “first, then.” Then shows what happens after the first step. For example, “First, read the instructions; then complete the exercise.” Than would be incorrect because the sentence is describing a sequence rather than comparing two things.

Why do people confuse Than and Then?

People often confuse than and then because the words look and sound very similar. They differ by only one letter, and fast typing can make the mistake even more common. However, their functions are different. Remembering that than signals comparison while then signals time, sequence, or consequence makes the distinction much easier.
