Short for lubricant; a slippery substance applied to surfaces to reduce friction and help things move more smoothly.
Shortened form of 'lubricant,' which comes from Latin 'lubricare' (to make slippery), itself from 'lubric-' (slippery) dating back to ancient Rome.
Lubricants are so important that entire industries exist just to make them better—from motor oil for engines to specialized lubes for robots, each needs different properties for different jobs.
