noun philology
late 14c., "love of learning," from O.Fr. philologie, from L. philologia "love of learning, love of letters," from Gk. philologia "love of discussion, learning, and literature," from philo- "loving" + logos "word, speech." Meaning "science of language" is first attested 1716; this confusing secondary sense has never been popular in the U.S., where linguistics (q.v.) is preferred.
