A fish is a creature that lives in water and has a tail and fins. There are many different kinds of fish.

Fish is the flesh of a fish eaten as food.

If you fish, you try to catch fish, either for food or as a form of sport or recreation.

If you fish a particular area of water, you try to catch fish in it.

If you say that someone is fishing for information or praise, you disapprove of the fact that they are trying to get it from someone in an indirect way.

If you feel like a fish out of water, you do not feel comfortable or relaxed because you are in an unusual or unfamiliar situation.

If you tell someone that there are plenty more fish in the sea, you are comforting them by saying that although their relationship with someone has failed, there are many other people they can have relationships with.

If you fish something out from somewhere, you take or pull it out, often after searching for it for some time.
