Had better… It’s time…

Had better (‘d better)

Use

We use had better to give strong advice or to tell someone (including ourselves) what to do.

• I‘d better go home. It’s getting late.
• You‘d better tell mum what happened before she finds out. 

Had better often implies that something negative will happen if something is not done and it often sounds like a threat or a warning.

• He‘d better give me my money back or he’ll be in trouble. 
• You‘d better behave yourself if you don’t want me to get really angry. 

Form

The word had is a past verb form, but the expression had better is only used to talk about the immediate future.

• You‘d better call me soon. I’ll be worried.

After had better we need to use infinitive without to.

Had better not (‘d better not) is the negative form of had better.

We can also use it’s (about) time + subject + past simple to say that someone should do something now or in the future.

• It’s time you went to the doctor.
