Francophile (adj.)

word-forming element meaning "French" or "the Franks," from Medieval Latin combining form of Franci "the Franks" (see Frank), hence, by extension, "the French." Used from early 18c. in forming English compound words.

also -phil, word-forming element meaning "one that loves, likes, or is attracted to," via French -phile and Medieval Latin -philus in this sense, from Greek -philos, common suffix in personal names (such as Theophilos), from philos "loving, friendly, dear; related, own," related to philein "to love," which is of unknown origin. According to Beekes, the original meaning was "own, accompanying" rather than "beloved."
