Need Not [Verb]How to use the expression "need not" correctly
Need not [verb] = “don’t need to [verb]”
This expression isn’t familiar to many younger English speakers, but it is an idiomatic expression that is perfectly acceptable (though old-fashioned). It is often used in contracted form: needn’t. Need does not change form to agree with the subject, and the verb following not is always an infinitive without to.
You needn’t worry about it; I’ve already taken care of it. = You don’t need to worry about it; I’ve already taken care of it.
Tell her she
needs need not bother going to the store; we already have what we need.
This same usage of need occurs in questions without to do:
Need I worry? = Do I need to worry?
