agent noun https://en.wikipedia.org/wiki/Agent_noun
An agentive suffix is commonly used to form an agent noun from a verb. Examples:
buffer 1894, from buffer (n.). Related: Buffered; buffering.
1835, agent noun from obsolete verb buff "make a dull sound when struck" (mid-16c.), from Old French bufe "a blow, slap, punch" (see buffet (n.2)); hence also "something that absorbs a blow."
