A parakeet is any one of many small to medium-sized species of parrot, in multiple genera, that generally has long tail feathers. Older spellings still sometimes encountered are paroquet or paraquet. In American English, the word parakeet usually refers to the budgerigar, which is one species of parakeet.
The name parakeet is derived from the French word perroquet. It is however a pseudo-francism as perroquet means parrot in French, while the French for parakeet is perruche.
