olive-oil

Its components trace back to a single, ancient Mediterranean source: the Greek word elaía for the olive tree and its fruit. This term passed into Latin as olīva and eventually into English as 'olive'. The word for the extracted liquid, 'oil', originates from the Greek elaion, meaning 'olive oil', derived from the same root elaía. Thus, the compound 'olive-oil' etymologically means 'oil from the olive', a meaning perfectly preserved from its classical origins, highlighting the olive's historical primacy as the quintessential source of edible and lamp oil in the ancient world.
