make sure (about) whether

[ademoglu]

Hi,

- She wants to make sure whether you wrote sentences in a correct way or not.
- She wants to make sure about whether you wrote sentences in a correct way or not.
- She wants to make sure that you wrote sentences in a correct way.

I would like to ask if we must use 'whether / about whether' after 'make sure' or not. I think we can use them but I am not that sure.

Thanks.

In every case you you should use "the" or "your" before sentences. Having said that I think they are all acceptable. From most to least natural, my preference is 3, 2 and 1.

I am not fond of "make sure about whether...or not" or "make sure whether... or not". When you say "whether...or not" there is built-in uncertainty.

I prefer #3.
