This paper looks at the evolution of how the word “lesbian”, originally simply a geographic/ethnic identifier meaning “person from the island of Lesbos” came to pick up a separate meaning of “female homosexual.”
Gilhuly begins with a (very brief) discussion of the abstract uses of locational and geographic language, how geographic signifiers very often acquire secondary meanings rooted in some association with the place (e.g., “Spartan accommodations”), and how classical Greek writers were highly prone to developing these sorts of metonymic geographic shorthands.
