Morphology

lubricator = lubricate (semi-transparent) = lubricate + or

Built from 'lubricate' + the agentive suffix '-or', but the sense 'a substance' is less predictable (learners expect 'lubricant' for the substance).

Etymology

The word lubricator comes from the Latin root lubric- meaning 'slippery', and you can see the same root in lubricate and the everyday word lube. A lubricator is therefore a substance that makes surfaces 'slip' and so reduces friction to keep moving parts smooth.
