This week’s question comes from Yu Chaojun in Xi’an who wants to know more about the expression do’s and don’ts.

Callum from BBC Learning English explains to us that do’s and don’ts are basically things you should do and shouldn’t do.

	A sign saying what you shouldn't do

So for example, at your place you work, some do’s and don’ts might be:

Do call your manager if you are going to be late.

Don’t leave your computer switched on at work.

It is merely another way of listing rules, often using ‘do’ in the imperative form. Imperatives are verbs used to give orders or instructions.

You might hear people talk about the do’s and don’ts of doing a particular thing.

"Here are some do’s and don’ts at the swimming pool – don’t run, do wear a swimming cap."

"Safe cycling: do’s and don’ts – you should always wear bright clothes, you must never cycle through a red light."

	Some do's and don'ts

Do’s and don’t are sometimes seen on signs or notices to help you, but more often than not you will hear the expression do’s and don’ts in conversation and people talking about what you should and shouldn’t do in different situations.

Take note of how it’s written too – make sure you put the apostrophes in the right places.

Thanks for your question Chaojun. We hope the answer helped you.
