guinea
UK: ˈɡɪni | US: ˈɡɪni
n. 1. A former British gold coin worth 21 shillings (now obsolete).
n. 2. A term used in the names of certain animals or plants, often implying African origin (e.g., guinea fowl, guinea pig).
n. 3. Informal term for a pound sterling (historical usage, chiefly British).
The word "guinea" traces back to the 17th century, when British gold coins were minted using gold from the Guinea coast of West Africa. The name stuck even after the coin's discontinuation, later extending to animals like the "guinea fowl" (imported from the region) and the "guinea pig" (misleadingly named, as it originated in South America). The informal use for "pound sterling" reflects the coin's historical value.
