Attantion; a modal is used with a verb word. A verb word is the dictionary form of the verb. In some grammar books, the verb word is called the bare infinitive because it appears without the word to. Verb words are very important in many patterns, but they are used most often with modals. The pattern is written below:
S + modal + verb word
His family might visit us

Avoid an invinitive or an –ing form instead of a verb word after a modal.
