- ‘Their‘ is the possessive pronoun form of ‘they‘, and indicates belonging, possession, or association.

| There | Stay there! I will be right back! |
| They’re | They’re the cutest puppies ever! |

10. Accept vs Except
Do you accept a job or except it? Accept is a transitive verb that means “to receive (something offered) willingly: I’ll accept her gift; an idea that is widely accepted“.
Except is a preposition that means “with the exclusion of”. For example, ‘we are open every day, except Sundays‘.

Do you want to allocate resources amongst a group? If not, the correct choice is probably a lot (with a space between).

13. Ensure, Assure, Insure
These words are the same, but different. To assure is similar to reassure, and has to do with giving someone confidence or assurance about something. Ensure is to make certain of something, whereas to insure pertains more to insurance (as in, ‘Is this house insured?’)
This is a tricky one. To understand the distinction better, we recommend reading the post on the difference between assure, insure and ensure.
