Must the verb that follow let always be an infinitive regardless of the context, even in a reported speech? For example,

Is that correct?

Best Answer

TO LET is not a modal verb. It is different from them semantically and formally.

  1. "Modality is about a speaker’s or a writer’s attitude towards the world.

A speaker or writer can express certainty, possibility, willingness, obligation, necessity and ability by using modal words and expressions.

Speakers often have different opinions about the same thing.
