If I want to say someone that I don't premise him about that, it says, I want to give him nothing about permission. what's out of the following four is the correct?
For example:
a) I think I'll finish the procedure today but I don't promise nothing. (or maybe I don't want to promise is more idiomatic)
b) I think I'll finish the procedure today but I don't promise anything.
Now, if I say "nothing" I'm confused whether it's considered a multiple negation or not, because if it is, then I basically say the opposite of what I want. And if I say "anything" it sounds to me like I say something like "I don't promise you anything in the world but I do promise something anyway.".
By the way I'm also confused about the words, something and everything in this context.
c) I think I'll finish the procedure today but I don't promise something.
d) I think I'll finish the procedure today but I don't promise everything.
