"Enough" and "though" are actually used separately, I think. They should usually be separated by a comma. "Enough" means...well, I assume you know! And "though" means "but." An example: I have some money. Not enough, though. I made dinner this evening. Not enough, though, for everyone. Where you say "not enough, though," you could also use "But not enough." It means the same thing. (i.e. I have some money, but not enough.) I hope that helped! ^^

I love to eat pancakes, but I've just eaten 300 of them and I think I can eat 20 more. However, for today, I think eating 300 pancakes is enough though.
