Oil \Oil\ (oil), n. [OE. oile, OF. oile, F. huile, fr. L. oleum; akin to Gr. ?. Cf. Olive.] Any one of a great variety of unctuous combustible substances, more viscous than and not miscible with water; as, olive oil, whale oil, rock oil, etc. They are of animal, vegetable, or mineral origin and of varied composition, and they are variously used for food, for solvents, for anointing, lubrication, illumination, etc. By extension, any substance of an oily consistency; as, oil of vitriol.

The vegetable oils are of two classes, essential oils (see under Essential), and natural oils which in general resemble the animal oils and fats.
