friend (n.): Old English freond "one attached to another by feelings of personal regard and preference," from Proto-Germanic *frijand- "lover, friend" (cognates: Old Norse frændi, Old Danish frynt, Old Frisian friund, Dutch vriend, Middle High German friunt, German Freund, Gothic frijonds "friend"), from PIE *priy-ont-, "loving," 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 they are not directly related to one another (see fiend). Related: Friends.
hold (v.): Old English haldan (Anglian), healdan (West Saxon), "to contain, grasp; retain; foster, cherish," class VII strong verb (past tense heold, past participle healden), from Proto-Germanic *haldan (cognates: Old Saxon haldan, Old Frisian halda, Old Norse halda, Dutch houden, German halten "to hold," Gothic haldan "to tend"), originally "to keep, tend, watch over" (as cattle), later "to have." Ancestral sense is preserved in behold. The original past participle holden was replaced by held beginning 16c., but survives in some legal jargon and in beholden.

Hold back is 1530s, transitive; 1570s, intransitive; hold off is early 15c., transitive; c. 1600, intransitive; hold out is 1520s as "to stretch forth," 1580s as "to resist pressure." Hold on is early 13c. as "to maintain one's course," 1830 as "to keep one's grip on something," 1846 as an order to wait or stop. To hold (one's) tongue "be silent" is from c. 1300. To hold (one's) own is from early 14c. To hold (someone's) hand "give moral support" is from 1935. Phrase hold your horses "be patient" is from 1844. To have and to hold have been paired alliteratively since at least c. 1200, originally of marriage but also of real estate.
safe (adj.): c. 1300, "unscathed, unhurt, uninjured; free from danger or molestation, in safety, secure; saved spiritually, redeemed, not damned;" from Old French sauf "protected, watched-over; assured of salvation," from Latin salvus "uninjured, in good health, safe," related to salus "good health," saluber "healthful," all from PIE *solwos from root *sol- "whole" (cognates: Latin solidus "solid," Sanskrit sarvah "uninjured, intact, whole," Avestan haurva- "uninjured, intact," Old Persian haruva-, Greek holos "whole").

As a quasi-preposition from c. 1300, on model of French and Latin cognates. From late 14c. as "rescued, delivered; protected; left alive, unkilled." Meaning "not exposed to danger" (of places) is attested from late 14c.; of actions, etc., "free from risk," first recorded 1580s. Meaning "sure, reliable, not a danger" is from c. 1600.
