- friend (n.)
- Old English freond "friend," from Proto-Germanic *frijand- "lover, friend" (cognates: Old Norse frændi, Old Frisian friund, Middle High German friunt, German Freund, Gothic frijonds "friend"), from PIE *priy-ont-, present participle form of root *pri- "to love" (see free (adj.)).
Meaning "a Quaker" (a member of the Society of Friends) is from 1670s. Feond ("fiend," originally "enemy") and freond often were paired alliteratively in Old English; both are masculine agent nouns derived from present participle of verbs, but are not directly related to one another (see fiend). Related: Friends.
