the usual Old English word for "river, running water" (still in use in Lancashire, according to OED), from Proto-Germanic *ahwo- (source also of Old Frisian a,Old Saxon aha,Old High German aha,German ahe-,Old Dutch aha,Old Norse "water"), from PIE root *ekweh- "water" (see aqua-). "The standard word in place-names for river denoting a watercourse of greater size than a broc or a burna" [Cambridge Dictionary of English Place-Names].

river (n.)

early 13c. (late 12c. in surnames), "a considerable body of water flowing with perceptible current in a definite course or channel," from Anglo-French rivere, Old French riviere "river, riverside, river bank" (12c.), from Vulgar Latin *riparia "riverbank, seashore, river" (source also of Spanish ribera, Italian riviera), noun use of fem. of Latin riparius "of a riverbank" (see riparian).

The generalized sense of "a copious flow" of anything is from late 14c., as is figurative use. The Old English word was ea "river," cognate with Gothic ahwa, Latin aqua (see aqua-). Romanic cognate words tend to retain the sense "river bank" as the main one, or else the secondary Latin sense "coast of the sea" (compare Riviera).

U.S. slang phrase up the river "in prison" (1891) is said to be originally in reference to Sing Sing prison, up the Hudson River from New York City. The phrase down the river "done for, finished" (1893) perhaps echoes the sense in sell down the river (1836, American English), originally of slaves sold from the Upper South to the harsher plantations of the Deep South.
