The story of the word

For a Greek speaker ἔλαιον meant one thing only, the pressed juice of the olive; every later oil in the language is an extension of that single crop. Latin turned it into oleum, Old French into oile, and English generalised it until it could cover whale blubber and North Sea crude. Petroleum is the compromise word that resulted, rock-oil, half Latin and half Greek, coined when miners kept finding a burnable liquid where no olive had ever grown.
