Morphology

unlubricated = lubricated (transparent) = un + lubricate + ed

Formed by applying the negative prefix 'un-' to the adjective 'lubricated' (from 'lubricate' + -ed), a straightforward negation.

Etymology

The word unlubricated breaks into un- meaning 'not' and lubricate meaning 'to make slippery', which you can also see in the common word lubricant. So unlubricated means 'not made slippery', which is why moving parts can stick, wear out, or make loud noises.
