Etymology

Origin of canary

First recorded in 1585–95; from Spanish (Isla) Canaria, from Latin Canāria (insula) “Dog (Island),” from can(is) “dog” ( see also hound) + -āria, feminine of -ārius -ary

Explanation

A canary is a small songbird, a finch known for its bright yellow feathers and beautiful singing. The word canary may also refer to a police informant, a singer, or a specific shade of yellow. The canary is named after the Canary Islands, the native lands of this cheerful bird. Wild canaries vary in color, including mixtures of brown, red, black, white, and yellow. Domesticated canaries, commonly kept as pets, are usually of the yellow variety — hence the name of the color called canary. Because canaries are known for singing, people sometimes call a female singer a canary, or they may use the term to refer to a person who helps police by "singing" or snitching on others.
