Difference Between Shall and May (With Table)

Communication plays a very important role as it helps us convey our feelings, thoughts and get our work done. To communicate properly, our usage of language and grammar needs to be good. Grammar is known as a structural foundation. It helps us to convey the precise meaning and avoids confusion.

If grammar is not used properly, the meaning of the message can change and hence one should know the correct usage of words according to the context. Grammar has eight parts of speech. Each has a different meaning according to its usage. Shall and may are two examples of modal auxiliary verbs.

Shall vs May

The difference between shall and may is that shall is used when you give a command or tell something inevitable, whereas may is used when one needs to ask permission and something is optional (not a command). Shall is mandatory, whereas may is used when it is left on an individual to make a decision.

Shall is a modal verb that is used with the base form of the main verb. The word shall is used to predict something, announce decisions or make offers, also used in legal writing. Shall acts like a command, something that is mandatory. It is used to express something likely to happen in the future.

May is a modal auxiliary verb that is used after the subject and before another verb. The word may is used to ask, give or refuse permission about a possibility or probability, also used in formal writing (academic or legal writing). It is sometimes used interchangeably with ‘can’. May is discretionary. The sentence used after May is refused as optional.
