An animal that lives in water and breathes through gills. Also used as a food, especially popular as 'fish and chips'.

As food: uncountable — 'I eat fish on Fridays.' As an animal, the plural is usually 'fish' (not 'fishes'): 'There are five fish in the tank.' Common collocations: fish and chips, fish tank, fish market, big fish (important person).

'Fish and chips' is one of the most iconic British dishes — battered fish fried and served with chips (thick fries). It is traditionally wrapped in paper. Eating fish on Fridays is a tradition in Catholic communities in English-speaking countries.
