guinea pig

Pronunciation RealAudio

guinea pig (GIN-ee pig) noun

1. A small rodent of the genus Cavia.

2. Someone or something used as a subject of experimentation.

[Sense 2 from the fact the guinea pigs were formerly used for experimentation.]

A guinea pig is neither from Guinea (West Africa) nor is it a pig. Rather it's a rodent from South America. Why that name? There's no consensus on how Guinea came into its name though a guinea pig does appear to squeal like a pig. They were earlier used in labs. Nowadays mice and rats have replaced them as subjects of tests and trials even though alternatives to animal testing are usually available.
