What is a -keeper?
-keeper combines "keep" (to guard, maintain, tend) with "-er" (agent suffix). A -keeper is someone whose responsibility is to guard, maintain, or manage something on a continuing basis:
Guardians of places or access:
• gatekeeper = one who guards a gate or controls access
• lighthouse keeper = one who tends a lighthouse
• innkeeper = the owner or manager of an inn
• shopkeeper = the owner of a shop
• groundskeeper = one who maintains sports grounds
Guardians of animals or systems:
• beekeeper = one who keeps bees
• zookeeper = one who cares for zoo animals
• gamekeeper = one who manages hunting grounds
Guardians of time, peace, or order:
• timekeeper = one who records time in a competition
• peacekeeper = one who maintains peace in a conflict zone
• scorekeeper = one who records the score in a game
Gatekeeper: beyond the gate
"Gatekeeper" has acquired a powerful metaphorical use in sociology, communications, and management:
In media, the "gatekeeper" is whoever decides which news reaches the public. In medicine, the GP acts as a gatekeeper controlling access to specialists. In organizations, gatekeepers are those who decide what information or which people reach higher levels.
"Gatekeeping" (the act of being a gatekeeper) now appears in social media discourse to describe those who exclude others from a community or interest: "gatekeeping" in fan communities for music, film, or sport.
Lighthouse keeper: the supreme literary image
The "lighthouse keeper" is one of the most symbolically charged images in English literature: the solitary figure tending the light amid darkness and sea, symbolizing loneliness, duty, guidance, and hope.
Virginia Woolf used "To the Lighthouse" (1927) as the title of one of her most important novels. The lighthouse as an unreachable goal and the keeper as guardian of time and light permeate the English literary tradition.
