Question

Function of modal auxiliary could function

Answer 1

A modal verb is a word that is used to represent the possibility, obligation, intensity, or permission of an action.

The use of modal verbs in English grammar:

• Modal verbs are also called 'Auxiliary verbs.'
• In English grammar, we use 8 principal modal verbs: will, shall, can, could, would, should, might, and must.
• These are used as helping verbs along with the main verb.
• The modal verbs 'may' and 'can' are used to seek permission for something.
• 'Might' 'would' and 'could' are used to show the possibility of happening something.
• 'should' and 'must' are used in the sense of an obligation.
