We use had better for the present and future, but not the past. The verb hadВ of had betterВ cannot be changed to have. Had better is used to issue warning, give advice, make suggestion, recommend an action that will avoid something bad that is likely to happen, or to say something that should be done or is worth doing in a particular situation. When a semi-modal verb is used with a third-person singular subject, it does not change its form. Both these verbs are always followed by infinitives. They cannot be used to form infinitives with the exception of ought toВ and used to. Semi-modal verbs do not have simple past tense, present participles, or past participles.

They are different from modal verbs, though, because they behave more like typical verbs - for example, they change to agree with their subjects, they change tense, and they can be combined with other helping verbs like be, have. Semi-modal verbs are used with main verbs, but they cannot be used as main verbs by themselves. Semi-Modal Verbs function in much the same way as modal verbs - they are an auxiliary verb that adds information to the main verb, but can't really function alone. The bare form of the main verb always follows the semi-modal verbs which are had better, ought to, used to, dare, and need. Semi-modal verbs combine with the preposition to to express about the same things as the main modal verbs.
