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

“Than” and “then” are two commonly confused English words because they sound similar in some accents but have completely different meanings and grammatical roles. Than is mainly used for comparisons, while then usually refers to time, sequence, or a result. Understanding this simple difference can make your writing clearer and more accurate.

Comparison Overview

Than and then are both extremely common English words, but they should not be used interchangeably.

The easiest way to understand the difference is to remember their primary functions:

• Than is generally used when comparing two or more things, people, actions, or qualities.
• Then is generally used to describe a time, sequence, consequence, or next step.
• Than often appears after comparative words such as better, faster, taller, smaller, and more.
• Then often tells us what happened next or what happened at a particular time.
• Neither word is a verb or noun in ordinary modern usage; both mainly function as grammatical connectors or adverbs, depending on the sentence.

Compare these examples:

• My car is faster than yours.
• We finished dinner and then watched a movie.

The first sentence makes a comparison. The second describes what happened next.

Definition of Than

Than is a word primarily used to introduce the second part of a comparison. It connects two things that differ in degree, amount, quality, size, preference, or another characteristic.

For example:

Sarah is taller than Emily.

Here, than introduces Emily as the person being compared with Sarah.

You will commonly see than after comparative adjectives and adverbs:

• better than
• faster than
• older than
• younger than
• more interesting than
• less expensive than
• more carefully than
• earlier than

What Does Than Mean?

In simple terms, than means something like “in comparison with.”

Examples:

• This book is better than the previous one.
• He runs faster than me.
• The blue bag is cheaper than the red one.
• Learning grammar is easier than I expected.
• She arrived earlier than everyone else.

In each sentence, than establishes a comparison.

Grammatical Role of Than

Than is traditionally treated as a conjunction or preposition, depending on how it is used in a sentence.

As a conjunction:

• She is older than I am.
• He works harder than I do.

As a preposition in common usage:

• She is taller than me.
• The company hired more employees than us.

The exact grammatical analysis can vary depending on the construction, but for everyday writing, the key point is simple: use than when you are comparing things.

Definition of Then

Then is primarily an adverb. It usually refers to time, sequence, or a consequence.

It can mean “at that time,” “next,” “after that,” or “in that case,” depending on the context.

Examples:

• I lived in London then.
• Finish your homework, then you can play.
• First, add the flour; then add the milk.
• If you are tired, then take a break.

Unlike than, then does not normally introduce a comparison.

What Does Then Mean?

Think of then as a word connected with time, order, or result.

For time:

• I was younger then.
• We lived there then.

For sequence:

• First, wash the vegetables. Then, cut them.
• She finished her work and then went home.

For a result or consequence:

• If you agree, then we can begin.
• If the store is closed, then we will come back tomorrow.

Grammatical Role of Then

Then is most commonly an adverb.

It can modify a verb or describe when an action happens:

• We then returned home.
• He then explained the problem.
• I was living in New York then.

It can also connect ideas in a sequence:

• First, read the instructions. Then, complete the exercise.

Main Differences Between Than and Then

The most important difference is their meaning and function.

Word	Main Function	Basic Meaning	Common Pattern	Example
Than	Comparison	In comparison with	comparative + than	She is taller than me.
Then	Time/sequence/result	At that time, next, or in that case	action + then	Eat breakfast, then leave.

Than = Comparison

Use than when one thing is being compared with another.

• My house is larger than yours.
• This test is easier than the last one.
• He is more experienced than his colleague.

Then = Time or Sequence

Use then when you mean something happened afterward or at a particular time.

• We had lunch and then went shopping.
• I was working there then.
• First, save the document. Then close the program.

Than and Then Are Not Interchangeable

Replacing one word with the other can change the meaning or make the sentence grammatically incorrect.

Incorrect:

• She is taller then me.

Correct:

• She is taller than me.

Incorrect:

• First, finish the report than send it.

Correct:

• First, finish the report then send it.

A useful test is to ask yourself:

Am I comparing something? Use than.

Am I talking about time, order, or a result? Use then.

Common Mistakes Learners Make

Mistake 1: Using Then for a Comparison

Incorrect:

• My car is faster then yours.

Correct:

• My car is faster than yours.

Why? The sentence compares two cars.

Mistake 2: Using Than for Sequence

Incorrect:

• Finish your homework, than watch television.

Correct:

• Finish your homework, then watch television.

Why? The sentence describes two actions in order.

Mistake 3: Confusing “More Than”

The phrase more than is a comparison or quantity expression.

• She has more books than I do.
• The repair cost more than expected.

Do not replace than with then.

Mistake 4: Confusing “Then” With “At That Time”

When you mean “at that time,” use then.

Simple Rules to Remember

Use these quick rules:

1. Than = comparison.
2. Then = time or sequence.
3. Than often follows comparative words.
4. Then often means “next” or “after that.”
5. Then can also mean “in that case.”
6. If you can replace the word with compared with, use than.
7. If you can replace it with next, after that, or at that time, use then.

Quick Tips for Writing and Speaking

A simple memory trick is:

Than = Compare

Both words begin with T, but associate than with comparison.

Another useful trick:

Then = Time

Think of the phrase “back then” or “what happened then?”

When proofreading, look for comparative words such as:

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

If one appears before the blank, than is often the correct choice.

When the sentence describes what happens next, then is usually correct.

When to Use Each One

When to Use Than

Use than when comparing:

• people
• objects
• prices
• sizes
• quantities
• abilities
• qualities
• performance
• preferences
• degrees of something

Examples:

• This route is shorter than the other one.
• Tea is cheaper than coffee here.
• The new system works better than the old one.

When to Use Then

Use then when discussing:

• past time
• future sequence
• instructions
• events happening afterward
• consequences
• conditional results

Examples:

• I lived there then.
• Finish the form and then submit it.
• If you agree, then we can proceed.

When NOT to Use Each One

When Not to Use Than

Do not use than merely because two actions happen one after another.

Incorrect:

• First, log in than open your account.

Correct:

• First, log in then open your account.

The sentence describes sequence rather than comparison.

When Not to Use Then

Do not use then to introduce the second element of a comparison.

Incorrect:

• My sister is younger then me.

Correct:

• My sister is younger than me.

The sentence compares ages, so than is required.

A Quick Substitution Test

If you are unsure, substitute another phrase.

For than, try:

compared with

Example:

• This phone is cheaper than that one.
• This phone is cheaper compared with that one.

For then, try:

next / afterward / at that time

Example:

• We went home then.
• We went home afterward.

If the substitution makes sense, you have probably chosen the correct word.

FAQs:

What is the difference between than and then?

Than is mainly used to make comparisons, while then usually refers to time, sequence, or a consequence. For example, “This car is faster than mine” uses than for comparison. “We ate dinner and then watched a movie” uses then to show what happened next. Their meanings and grammatical functions are different.

When should I use than?

Use than when comparing two or more people, objects, actions, qualities, or amounts. It commonly follows comparative words such as better, faster, taller, smaller, more, and less. For example, “This book is more interesting than that one.” A useful reminder is that than is connected with comparison.

When should I use then?

Use then when referring to a time, sequence, or consequence. It can mean “at that time,” “next,” “after that,” or “in that case.” For example, “I lived there then” refers to a past time, while “Finish your homework, then relax” shows sequence.

Is it than or then in a comparison?

The correct word is than when making a comparison. For example, “John is taller than Mark” and “This option is cheaper than the other one.” If one person, object, quality, or amount is being compared with another, than is normally the appropriate choice.

Is it than or then for the next step?

Use then when describing the next step or action. For example, “Open the file, then click Save.” Here, then shows that clicking Save happens after opening the file. A helpful memory rule is that then often means “next” or “after that.”

Can than and then be used interchangeably?

No. Than and then have different meanings and grammatical functions, so they generally cannot replace one another. Using the wrong word can make a sentence incorrect or change its meaning. Use than for comparisons and then for time, sequence, or consequences.

Is then used for time?

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

Is than a comparative word?

Than is commonly used with comparative adjectives and adverbs, but it is not itself a comparative adjective. It introduces the second part of a comparison. Common examples include “better than,” “faster than,” “more useful than,” and “less expensive than.” Its main function is to connect the things being compared.

How can I easily remember than vs then?

Remember this simple rule: than = comparison, while then = time or sequence. If you can replace the word with “compared with,” choose than. If you can replace it with “next,” “afterward,” or “at that time,” choose then. This quick test works in most everyday sentences.

What is the correct sentence: “Better then” or “better than”?

The correct phrase is “better than” when making a comparison. For example, “This method is better than the old one.” The word then would be incorrect because the sentence compares two methods rather than describing time, sequence, or a consequence.
