far-flung (adj.)

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

c. 1300, "to dash, run, rush," probably from or related to Old Norse flengja "to flog," which is of uncertain origin, perhaps from Proto-Germanic *flang- (source also of Old Swedish flenga "strike," Danish flænge "slash, gash"), from a nasalized variant of PIE root *plak- (2) "to strike." Meaning "to throw, cast, hurl" is from mid-14c. An obsolete word for "streetwalker, harlot" was fling-stink (1670s). Related: Flung; flinging, but in Middle English with past tense flang, past participle flungen.
