O.E. freo "free, exempt from, not in bondage," also "noble, joyful," from P.Gmc. *frijaz (cf. M.H.G. vri, Ger. frei, Du. vrij, Goth. freis "free"), from PIE *prijos "dear, beloved" (cf. Skt. priyah "own, dear, beloved," priyate "loves;" O.C.S. prijati "to help," prijatelji "friend;" Welsh rhydd "free"). The adverb is from O.E. freon, freogan "to free, love." The primary sense seems to have been "beloved, friend, to love;" which in some languages (notably Gmc. and Celtic) developed also a sense of "free," perhaps from the terms "beloved" or "friend" being applied to the free members of one's clan (as opposed to slaves, cf. L. liberi, meaning both "free" and "children"). Cf. Goth. frijon "to love;" O.E. freod "affection, friendship," friga "love," friğu "peace;" O.N. friğr, Ger. Friede "peace;" O.E. freo "wife;" O.N.
