1) She had better get out of here -- CORRECT ('had better' + bare infinitive) ('had better' = ' 'd better') 2) She had better gets out of here -- INCORRECT
Is that what you need to know?
is there any difference between "had better" and "had best"?
If you had better to do something, it is advisable or prudent to do it. If you don’t, there will be a problem or a danger: You’d better see a doctor, O.K.? If you had best to do something, it is the wisest to do it: You’d best stay at home till you get over that cold = You should stay at home till you get over that cold. Hope that helps!
2 Should have been "gets" instead of "ges". I am intrested in the correct way of writing grammatically. Is 1 grammatically OK too?
