Might (giving permission)

[Esgaleth]

I'd be grateful to know the difference between the two sentences in terms of giving permission. That is why 'might' can be used in the first sentence while is wrong in the second:

You ___________ leave if you've finished.
You ________ use my dictionary if you want.

Thanks in advance.

'Might' is unnatural in both, 'May' is possible.

I wouldn't use "might" in either sentence. I would use "may" or "can".

That was absolutely clear before I saw this (Q1) Could it possibly be a typo?

[5jj]

Could it possibly be a typo?

I'd call it simply a mistake.

Thanks, you did take a load off my mind.
On the other hand, critical thinking is what some are lacking Thanks for the lesson.
