MODAL VERBS AND THE FUNCTIONS

Modal verbs are special verbs (like must, have to, can, would, etc) which have certain function. Modals or modal auxiliary verbs are used to give the additional information or explanation about the function of the main verb that we use in a sentence. Modals have special characteristics.

They never change their form and they are always followed by infinitive without “to”. For example, we use “would go” not “would to go”. Commonly, modal verbs are used to express certainty, possibility, willingness, obligation, necessity, and ability.
