Common mistakes worth knowing
Their, there and they’re
Their shows ownership, there points to a place, and they’re means “they are”.
Its and it’s
It’s is short for “it is” or “it has”. Its is the possessive form, with no apostrophe.
Comma splices
Two complete sentences joined only by a comma should be split with a full stop or joined with a word such as “and” or “but”.
Fewer and less
Use fewer for things you can count and less for amounts you can’t.
Who it helps

- Names, technical terms and creative style choices may be altered, so use Show changes to catch anything you want to keep.
