far-reaching
UK: ˌfɑːˈriːtʃɪŋ | US: ˌfɑːrˈriːtʃɪŋ
adj. having a wide or significant effect or influence
adj. extending over a great distance
The word "far-reaching" combines "far," from Old English feorr (distant), and "reach," from Old English rǣcan (to extend). The suffix "-ing" transforms it into an adjective. The term emerged in the 17th century to describe things that extend physically or metaphorically over great distances or impacts. Its logic lies in the literal idea of "reaching far," later abstracted to describe widespread consequences.
