What Do Than and Then Mean

Although than and then look alike, they perform different jobs in a sentence.

What Does Than Mean

Than is a conjunction and sometimes a preposition used to compare two or more things.

It answers questions like:

• Which one is better?
• Which one is larger?
• Which one is faster?
• Which one is more expensive?
• Which one is different?

Examples:

• My car is faster than yours.
• She is taller than her brother.
• Coffee costs more than tea.
• This puzzle is harder than the last one.

In every example, than introduces the second part of a comparison.

What Does Then Mean

Then is an adverb, adjective, or noun that refers to time, order, or what happens next.

It answers questions like:

• What happened next?
• When did it happen?
• What is the next step?

Examples:

• Finish your homework, then watch television.
• We ate dinner and then went home.
• Back then, phones had no touchscreens.
• If it rains, then we’ll stay inside.

Each sentence uses then to show time or sequence rather than comparison.

In fast speech, than is often pronounced as thən, making it sound even more like then. This similarity is one reason these words are frequently confused in writing.

Word Origin

Learning where these words came from makes their meanings easier to remember.

Than

Than comes from Old English þonne, which was originally used to introduce comparisons. Over time, it became the standard conjunction for comparing people, objects, actions, and ideas.

Then

Then also comes from Old English þonne, but it developed a different meaning related to time, sequence, and what happens next.

Although both words share the same historical root, English gradually assigned each one a separate grammatical role.

Than vs Then in American and British English

The grammar rules for than and then are the same in both American and British English.
