What is a modal verb?
A modal verb or auxiliary verb is a verb, which modifies another verb, so that the modified verb has more intention in its expression. In essence the modal verb expresses modality, the way in which something is being said. Modal verbs are common in most languages of Germanic origin, including English. Typical modal verbs in English express possibility or necessity. Verbs like may or might are used to suggest that you are possibly going to do something but haven’t quite committed to the action yet. The statement, I might go to the movies is different than the statement I am going to the movies. In the former statement you are expressing the possibility of going to see a movie, and in the latter you express the decided intent of your action to see a movie. The modal verb might or in variant form may helps qualify and modify the verb go.
