Than vs Then is a common English grammar confusion because these two words sound similar but have completely different meanings and functions. Than is mainly used for comparisons, while then relates to time, sequence, or a result.
Understanding this simple difference will help you write clearer sentences and avoid one of the most common spelling mistakes in English.
Comparison Overview
Than and then are both extremely common English words, but they cannot normally be substituted for each other.
The easiest way to understand the difference is:
- Than = comparison
- Then = time, sequence, or result
For example:
- My car is faster than yours.
- We ate dinner and then watched a movie.
In the first sentence, than compares two things: my car and yours. In the second sentence, then shows what happened next.
Although the words differ by only one letter, their grammatical roles are distinct. This makes than vs then an especially important distinction for students, writers, professionals, and anyone learning English.
| Word | Main Function | Meaning | Example |
| Than | Comparison | Used to compare people, things, or amounts | She is taller than me. |
| Then | Time/sequence/result | At that time, next, or in that case | We finished work and then went home. |
A useful memory trick is:
Than compares. Then continues.
If you are comparing two things, choose than. If you are talking about what happened next, when something happened, or what follows from a condition, choose then.
Definition of Than
Than is a word used primarily to introduce the second part of a comparison.
It commonly appears after comparative adjectives and adverbs such as:
- bigger than
- smaller than
- faster than
- slower than
- better than
- worse than
- more expensive than
- less important than
- more quickly than
Examples of Than
- My brother is taller than me.
- This book is more interesting than that one.
- Sarah runs faster than John.
- Today is colder than yesterday.
- The new computer is better than my old one.
In each example, than connects two things being compared.
Than in Comparisons
The basic structure is:
comparative word + than + person or thing
For example:
This phone is cheaper than that phone.
Here, cheaper is the comparative adjective, and than introduces the thing being compared.
Another pattern is:
more/less + adjective + than
For example:
This lesson is more useful than the previous one.
Than can also be used with quantities:
More than fifty students attended the class.
It can even appear in expressions involving preference:
I would rather read than watch television.
The key idea remains the same: than is associated with comparison or contrast.
Definition of Then
Then is an adverb that commonly refers to time, sequence, or a consequence.
It can mean:
- At that time
- Next or afterward
- In that case
- As a result of a condition
Then Meaning “At That Time”
When then refers to a particular time, it means something similar to at that time.
Examples:
- I was living in London then.
- We did not know the answer then.
- She was a student then.
Then Meaning “Next”
Then frequently describes the next action in a sequence.
Examples:
- First, wash the vegetables, then cut them.
- Finish your homework, then play outside.
- We went to the restaurant and then visited the park.
Then Meaning “In That Case”
Then can also introduce a logical result.
Examples:
- If you are tired, then you should rest.
- If the store is closed, then we will come tomorrow.
- If you know the answer, then explain it to everyone.
In these examples, then connects a condition with its expected consequence.
Main Differences Between Than and Then
The central difference between than and then is their meaning.
Than Shows Comparison
Use than when comparing two or more people, objects, ideas, quantities, or situations.
Examples:
- Ali is older than Ahmed.
- This road is longer than the other one.
- Mathematics is easier for me than physics.
- She earned more money than her colleague.
Then: Shows Time or Sequence
Use then when talking about when something happened or what happens next.
Examples:
- I lived there then.
- We finished lunch and then left.
- First read the instructions, then begin the test.
Then Shows a Relationship Between Comparisons
Than often follows a comparative expression.
better than
larger than
more useful than
less expensive than
Then Shows Progression or Consequence
Then often indicates movement from one point to another.
First → then → next
For example:
First, open the website. Then, create an account.
It can also indicate a logical conclusion:
If you are ready, then we can begin.
Than vs Then in Grammar
Understanding the grammatical role of each word makes the distinction much easier.
Than as a Conjunction or Preposition
Than is commonly used to introduce the second element in a comparison.
Examples:
- She is taller than I am.
- He works harder than his brother.
- This option costs less than the other one.
Depending on the sentence structure, than can function as a conjunction or preposition.
Then as an Adverb
Then is generally an adverb.
It can modify an action by showing when it happens:
We lived there then.
It can show sequence:
We ate, then left.
It can also show a consequence:
If that is true, then we need another plan.
The important distinction is that than is connected to comparison, while then is connected to time, sequence, or logical consequence.
How to Tell Than and Then Apart
A simple test can help you decide which word to use.
Ask: “Am I Comparing?”
If the answer is yes, use than.
My laptop is faster than yours.
You are comparing two laptops, so than is correct.
Ask: “Am I Talking About What Happens Next?”
If the answer is yes, use then.
Finish the report and then send it.
You are describing a sequence, so then is correct.
Ask: “Can I Replace It With ‘At That Time’?”
If yes, use then.
I was younger then.
This means:
I was younger at that time.
Ask: “Can I Replace It With ‘Compared With’?”
If yes, use than.
This car is cheaper than that one.
The comparison makes than the correct choice.

FAQs
What is the difference between than and then?
Than is mainly used to make comparisons, while then is used to describe time, sequence, or a result. For example, “She is taller than me” compares two people. “She finished her work and then went home” shows a sequence of events. Remembering this basic difference makes it easier to choose the correct word.
When should I use than?
Use than when comparing two or more people, things, qualities, quantities, or situations. It commonly follows comparative words such as better, bigger, faster, older, more, and less. For example, “This computer is faster than my old one.” The word than introduces the second part of the comparison.
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 relax” shows sequence. It can also appear in conditional structures such as “If it rains, then we will stay home.”
Is it more than or more then?
The correct expression is more than. Here, than introduces a comparison involving quantity or amount. For example, “The company has more than one hundred employees.” Then would be incorrect because the sentence is not describing time, sequence, or a consequence. This is one of the most common than vs then mistakes.
Is it better than or better then?
The correct phrase is better than because better is a comparative adjective. For example, “This method is better than the old method.” Since the sentence compares two methods, than is required. Using then would incorrectly suggest time or sequence rather than comparison.
How can I easily remember than vs then?
A simple memory rule is: than compares; then continues. If your sentence compares two things, use than. If it explains what happens next, refers to a time, or shows a result, use then. For example, “She is faster than me” uses than, while “She ran and then stopped” uses then.
Can then mean “at that time”?
Yes. Then can mean “at that time” when referring to a particular moment or period. For example, “I was living in Canada then” means “I was living in Canada at that time.” This usage is different from than, which is primarily connected with comparisons and does not carry a time-related meaning.
Can than be used without a comparison?
Than is most commonly associated with comparisons, but it can appear in structures where the comparison is understood from context. For example, “I would rather walk than drive” expresses a preference between two actions. The important point is that than connects contrasting or comparative elements, while then relates to time, sequence, or consequence.
What is the difference between if then and more than?
If…then expresses a condition and its result, so it uses then. For example, “If you study, then you may improve your results.” More than expresses quantity or comparison, so it uses than, as in “She has more than five books.” The meaning of the sentence determines which word is correct.
Why do people confuse than and then?
People often confuse than and then because the words look and sound very similar, especially in fast speech. However, their functions are different. Than relates to comparison, while then relates to time, sequence, or consequence. Focusing on the meaning of the sentence instead of pronunciation is the easiest way to avoid this confusion.
