A should and shouldn’t — giving advice

You should get some rest.

You shouldn’t work so hard.

You should do something = it is a good idea or the right thing to do. You shouldn’t do something = it is not a good idea to do it.

should	a good idea / advice	You should drink more water.
shouldn’t	not a good idea	You shouldn’t skip breakfast.

💡 After should we use the base verb with no to: should go, should be — never should to go.

B I think / I don’t think / Do you think…?

We often give an opinion or ask for advice with these phrases:

I think … shouldI think you should see a doctor.

I don’t think … shouldI don’t think you should buy that car.

Do you think … should?Do you think I should call her?

natural I don’t think you should go. ✓

less natural I think you shouldn’t go. ✗

💡 To say something is not a good idea, move the negative onto think: I don’t think you should…

C ought to = should

You ought to apologise.

ought to has almost the same meaning as should. The big difference: ought keeps to before the verb.

keep “to” You ought to rest. ✓

common error You ought rest. ✗

ought to do	= should do	You ought to phone your grandmother.
ought not to do	= shouldn’t do	You ought not to believe every rumour.

💡 should + base (no to), but ought + to + base. The negative is ought not to / oughtn’t to.

D should = “I expect” (something probable)

should can also mean that something is probable — what we expect to be true now or in the future.

expected nowIt’s nine o’clock — the shop should be open.

expected in the futureShe has trained hard, so she should win.

advice → should / ought to not a good idea → shouldn’t I expect → should keep “to” → ought to

💡 They left early, so they should be home by now. (= I expect they are home)

📌

Remember — should / ought to = the right thing to do or good advice · shouldn’t = not a good idea · keep to after ought (ought to do) · should can also mean “I expect” (The train should arrive soon). Quick check: You should apologise (advice) is softer than You must apologise (no choice).
