Unless

Hi there,

Please I looked for the use of unless but I didn't find when NOT to use it .

1)Unless is used here.. I'll be back tomorrow unless there's A plane strike.

2) it's written that unless can't be used but I actually don't know why.

I'll be glad if she doesn't come this evening.

Could you please explain when NOT to use it, thanks A million

"X unless Y" usually implies that X is the normal/default/expected case, that will occur provided Y does not intervene to prevent it. In the "I'll be glad" sentence, being glad is not something that will occur as a default unless prevented: it will occur only in the specific case that she does not come.

??? ????????when NOT to use it.

There may be other reasons not to use "unless", but this idea explains the example you quoted. Generally speaking you don't use "unless" after "will be" plus an adjective that describes how someone's feelings will be affected if something happens.

1) I will be glad if she doesn't come this evening. OK.
