Hi, I'm Tim and I'm going to tell you the difference between too and enough when we use them as adverbs.
They refer to quantity but there's an important difference.
Enough is usually positive. It means that something is 'suitable or sufficient'.
Great this T-shirt is big enough. It'll fit me perfectly. It's colourful enough for my sister's party!
Too usually has a negative meaning. It's used to say that something is 'a problem' or 'it's unsuitable' in some way.
Oh no! This is too short! I can't wear this! It's too late to find anything else to wear.
So if we have enough, it's probably a good thing. But if you see too, it's a bad thing.
