Other forms: zoos
A zoo is the place where wild animals live in the city so people can see them. Go to the zoo, zoo keeper, a good zoo.
Modern ones justify themselves by conservation and breeding programmes rather than display, and some species survive only because of them — though the argument about whether that pays for the captivity is a live one. The word is a shortening of zoological garden. Note that a zoo is also any scene of noisy chaos.
