The word "omission" originates from Latin omissio, derived from omittere ("to let go, disregard"), which combines ob- (here meaning "away") and mittere ("to send"). The morpheme "miss" retains its core meaning of "send" (as in "mission" or "dismiss"), while the prefix "o-" (from ob-) implies negation or exclusion. Over time, "omission" evolved to signify the act of excluding or neglecting something, reflecting its Latin roots in deliberate inaction.
