lubricants
Slippery machine fluids
Lubricants are substances that reduce friction between surfaces in contact.
Motor oil lubricates engine parts; grease lubricates bearings and joints.
Personal lubricants facilitate sexual activity or medical procedures.
Figuratively, lubricants are things that make interactions smoother: Money is the lubricant of politics.
The singular lubricant works as both noun and adjective: lubricant gel.
