'Whether' is used to show we do not know if something is true or will happen. It often comes in questions inside a sentence, not direct questions.
I wonder whether it will rain today.
She asked whether he was coming.
We use 'whether or not' to say that something will happen in any case, no matter what the other choice or condition is. It shows two clear opposite possibilities.
We will go whether or not it rains.

'Whether' can show when someone is talking about a yes/no question with two choices. It introduces these questions inside sentences without quotation marks.

We use 'whether' to talk about not being sure about two different possibilities or to show both are possible. It often connects actions or states.

'Whether' can emphasize that something happens despite the condition or situation. It means the result is true in every case.
