Old English feorr "far, remote, distant" (cognates: Old Saxon fer, Old Frisian fer, Old Norse fjarre, Dutch ver, Old High German ferro, German fern), probably a development in western Proto-Germanic from the adverb (see far, adv.). Far East "China, Japan, and surrounding regions" is from 1838.

Old English feor "to a great distance, long ago," from Proto-Germanic *ferro (cognates: Old Saxon fer, Old Frisian fir, Old Norse fiarre, Old High German fer, Gothic fairra), from PIE *per (1), base of words for "through, forward," with extended senses such as "across, beyond" (cognates: Sanskrit parah "farther, remote, ulterior," Hittite para "outside of," Greek pera "across, beyond," Latin per "through," Old Irish ire "farther"). Paired with wide since 9c.
