FAQs
What is the difference between than and then?
The main difference is their purpose. Than is used to compare people, objects, or ideas, while then refers to time, sequence, or the next step in a process. Remember that comparisons use than, and actions that happen afterward use then.
Is “better then” or “better than” correct?
The correct phrase is better than because the word better creates a comparison. Whenever you compare two things, than should follow the comparative adjective. Better than is a common spelling mistake and is grammatically incorrect.
Can then ever be used for comparisons?
No. Then is not used to compare people, objects, or ideas. It only refers to time, order, or sequence. If your sentence compares one thing with another, you should always use than instead.
