Old English freo "free, exempt from, not in bondage," also "noble; joyful," from Proto-Germanic *frijaz (cf. Old Frisian fri, Old Saxon and Old High German vri, German frei, Dutch vrij, Gothic freis "free"), from PIE *prijos "dear, beloved," from root *pri- "to love" (cf. Sanskrit priyah "own, dear, beloved," priyate "loves;" Old Church Slavonic prijati "to help," prijatelji "friend;" Welsh rhydd "free").

Latin liberi, meaning both "free" and "children").
