Than vs. then is a common English grammar confusion because the two words sound similar but have completely different meanings and jobs in a sentence. Than is mainly used for comparisons, while then relates to time, sequence, or a result. Understanding this simple difference can make your writing and speaking much clearer.
Comparison Overview
Than and then are both common English words, but they should not be used interchangeably. Their similar pronunciation often causes confusion, especially when writing quickly.
The easiest way to understand them is:
- Than = used when comparing two or more things.
- Then = used to talk about time, order, sequence, or what happens next.
For example:
Sarah is taller than Emma.
Here, than connects two things being compared.
We finished dinner, and then we watched a movie.
Here, then shows what happened next.
Although the difference looks small, choosing the wrong word can change the meaning or make a sentence grammatically incorrect.
Definition of Than
Than is a conjunction or preposition commonly used to introduce the second part of a comparison. It helps show how one person, object, action, or idea differs from another.
For example:
My car is faster than yours.
The sentence compares two cars, so than is correct.
What Does Than Mean?
The word than essentially introduces the person or thing that is being compared with something else.
Common comparison structures include:
- taller than
- shorter than
- faster than
- slower than
- better than
- worse than

- less expensive than
- older than
- younger than
Examples of Than

In every example, than introduces a comparison or preference.
Definition of Then
Then is an adverb that commonly refers to a particular time, an event that follows another event, or a result that follows a condition.
For example:
We went to school and then came home.
Here, then means “after that.”
It can also refer to a past or future time:
Back then, people did not have smartphones.
What Does Then Mean?
The word then can have several related meanings:
- At that time
- After that
- Next
- In that case
- As a result
For example:

Another example is:

Examples of Then

| Than | Comparison | Used to compare things | John is taller than Mark. |
| Then | Time/sequence | After that or at that time | We ate dinner then left. |

With these rules and examples, you can confidently distinguish than from then in everyday conversation, academic writing, professional communication, and formal English.
Conclusion :
Understanding Than vs Then becomes much easier when you remember the main job of each word. Than is used when you compare people, objects, ideas, qualities, or actions, as in “This book is better than that one.” Then, on the other hand, is used to talk about time, sequence, or a result, as in “We finished dinner and then watched a movie.” Although these words sound similar, they cannot normally replace each other without changing the meaning or making a sentence incorrect.

Once you recognize whether your sentence compares something or describes what happens next, choosing the correct word becomes natural. With regular practice, you can confidently use than and then in conversations, schoolwork, professional writing, emails, and everyday communication.
FAQs
What is the main 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, “Sarah is taller than Emma” uses than because two people are being compared. “Sarah finished her work and then went home” uses then because it describes what happened next.
When should I use than?
Use than when comparing two or more people, objects, ideas, qualities, or actions. It commonly follows comparative words such as better, faster, taller, older, smaller, and more. For example, “My new laptop is faster than my old one.” The word than connects the thing being described with what it is compared against.
When should I use then?
Use then when talking about time, order, or a consequence. It can mean “after that,” “at that time,” or “in that case.” For example, “We ate dinner and then watched television” uses then to show sequence. It can also appear in conditional sentences such as, “If you agree, then we can begin.”
Is than a preposition or conjunction?
Than can function as both a conjunction and a preposition, depending on how it is used. It commonly introduces the second part of a comparison. In “She is taller than me,” than works as a preposition in traditional grammatical analysis. In “She is taller than I am,” it introduces a clause and functions as a conjunction.
Is then always related to time?
Not always. Then frequently refers to time or sequence, but it can also introduce a result or consequence. For example, “Finish your homework, then play outside” indicates sequence. In “If the weather is bad, then we will stay home,” then means something similar to “in that case.” Its exact meaning depends on context.
Why are than and then confused?
Than and then are often confused because they look and sound very similar. However, their meanings and grammatical functions are different. Writers may accidentally choose then when making a comparison or than when describing a sequence. Focusing on meaning rather than pronunciation makes the distinction much easier to remember and apply correctly.
What is an easy way to remember than vs then?
A simple memory trick is that than = comparison and then = time or sequence. If you are comparing something, choose than: “This car is faster than mine.” If you mean “after that” or “next,” choose then: “We went shopping and then went home.” This quick test works in most everyday situations.
Can than and then ever be used interchangeably?
No. Than and then generally have different meanings and cannot be freely substituted. Using the wrong word can make a sentence grammatically incorrect or change its intended meaning. For example, “She is older than me” requires than, while “She arrived and then called me” requires then.
Which is correct: better than or better then?
The correct expression is “better than.” The word than is required because the phrase compares two things. For example, “This restaurant is better than the one we visited yesterday.” Using then in this construction is incorrect because then refers to time, sequence, or consequence rather than comparison.
Which is correct: first than or first then?
The correct expression is “first, then.” When explaining steps or events in order, then shows what happens after the first action. For example, “First, read the instructions, then complete the exercise.” Using than would be incorrect because there is no comparison being made between the two actions.
