Profuse is a word for a lot of something or even way too much — a profuse rainfall is a serious amount of rain.
This word has to do with extravagance or abundance. If you're bleeding profusely, you're bleeding a lot. If you lavish profuse gifts on your pet, you might have too much money on your hands. When you give someone profuse praise, you're probably laying it on a little thick. If you’re a farmer and your crops are profuse, that’s great because you have a lot of crops. Anything profuse is happening in great amounts.
