Word Origin & History
farO.E. feorr "to a great distance, long ago," from P.Gmc. *ferro (cf. O.N. fjarre, Du. ver, Ger. fern), from PIE *per- "through, across, beyond" (cf. Skt. parah "farther, remote, ulterior," Hitt. para "outside of," Gk. pera "across, beyond," L. per "through," O.Ir. ire "farther"). Far East "China, Japan,
and surrounding regions" is from 1852.
furtherO.E. furðor (adv.), furðra (adj.), (ge)fyrðan (v.) "further, impel," etymologically representing either "forth-er" or "fore-ther." The former would be from furðum (see
forth) + comp. suffix *-eron-, *-uron- (cf. inner, outer). Alternative etymology traces it
to P.Gmc. *furþeron-, from PIE *pr-tero, (cf. Gk. proteros "former"), from root of fore + comp. suffix also found in after, other. Senses of "in addition, to a greater extent" are later metaphoric developments. Related: Furthered; furthering.
