assist: assist: [15] Etymologically, assist means ‘stand by’. It comes, via French assister, from Latin assistere, a compound verb formed from the prefix ad- ‘near’ and sistere ‘stand’ (related to Latin stāre ‘stand’, from which English gets state, station, status, statue, etc). A remnant of this original meaning survives in the sense ‘be present without actually participating’, but the main use of the word in English has always been that which came from the metaphorical sense of the Latin verb – ‘help’.
=> state, station, statue, status
assist (v.): early 15c., from Middle French assister "to stand by, help, put, place, assist" (14c.), from Latin assistere "stand by, take a stand near, attend," from ad- "to" (see ad-) + sistere "stand still, take a stand; to set, place, cause to stand," from PIE *si-st-, reduplicated form of root *sta- "to stand" (see stet). Related: Assisted; assisting. Medical assisted suicide attested from 1884.
assist (n.): 1570s, "an act of assistance," from assist (v.). In the sporting sense attested 1877 in baseball, 1925 in ice hockey.
