Start with the essentials

Three common questions, explained without the jargon.

Its or it's?

It's is short for “it is” or “it has”. Its shows possession and has no apostrophe.

It's a useful book. Its cover is green.

Then or than?

Use then for time or sequence. Use than when comparing two things.

Read the note, then revise. This version is clearer than the first.

Commas in a list

Commas separate items in a list. A comma before the final “and” is optional in many styles; use it consistently and when it makes the meaning clearer.

Bring a notebook, a pen, and a dictionary.
