Etymology
the word 'lubrication' traces its lineage directly to the latin adjective lubricus, meaning 'slippery'. this term itself is thought to derive from the proto-indo-european root sleubh-, conveying the sense of slipping or sliding. the latin verb lubricare, 'to make slippery', was formed from this adjective, and the english noun 'lubrication' was built upon this verb by adding the productive suffix '-ation', which denotes the action or process. thus, the modern technical term for applying a friction-reducing substance retains the core logic of its ancient root: the act of making something slippery.
