We use “had better” plus the infinitive without
“to” to give advice. Although “had” is the past form of “have”, we use “had better” to give advice about the present or future
•I’d better get back to work
•We’d better meet early
The negative form is “had better not”
I’d better not come
We’d better not miss the start of his presentation
We use “had better” to give advice about specific situations, not general ones. If you want to talk about general situations, you must use “should”x
•You should brush your teeth before you go to bed
•I shouldn’t listen to negative people
•He should dress more appropriately for the office
•You shouldn’t say anything
I should get back to work
We should meet early
However, when we use “had better” there is a suggestion that if the advice is not followed, that something bad will happen
•You’d better do what I say or else you will get into trouble
I’d better get back to work or my boss will be angry with me
We’d better get to the airport by five or else
we may miss the flight
