greenskeeper

The word 'greenskeeper' is a modern compound noun originating in the early 20th century from the specialized vocabulary of golf. It is formed from 'greens', a plural noun referring specifically to the smooth, grassy putting areas on a golf course, and the agent noun 'keeper', derived from the verb 'to keep' in its sense of "to maintain or guard." The literal meaning, "one who keeps (maintains) the greens," transparently describes the professional's primary duty. This compound follows a classic English pattern for occupational titles, similar to 'gamekeeper' or 'shopkeeper', directly linking the place or object of care with the agent responsible for its upkeep.
