A fish out of water

Someone who feels uncomfortable or out of place in an unfamiliar situation

Meaning

A fish out of water describes a person who feels uncomfortable, awkward, or out of place because they are in a situation or environment that is unfamiliar to them. Just as a fish cannot survive on land, the person feels they do not belong. Literal: a fish removed from water. Figurative: a person in surroundings where they feel lost or unsuited.

Origin & History

The phrase draws on the simple, vivid image of a fish taken out of the water in which it lives. On land a fish flaps helplessly and clearly cannot cope, so the picture became an obvious symbol for a human being placed somewhere they are not adapted to.

The expression has been used in English for centuries; versions appear in the writings of Geoffrey Chaucer in the 14th century and John Wycliffe around the same period. It has remained popular ever since because almost everyone can imagine how badly a fish copes outside water, which makes the comparison instantly understandable.
