Originally from Latin, omittere (“to send”). Post-classical Latin introduced the term omission; from the past participial stem of omittere, omiss- and the suffix -ion. This word was taken into Middle French and subsequently Anglo-Norman which heavily influenced the English language.

- From Mark Twain, The Adventures of Huckleberry Finn:
- S’pose people left money laying around where he was—what did he do? He collared it. S’pose he contracted to do a thing; and you paid him, and didn’t set down there and see that he done it—what did he do? He always done the other thing. S’pose he opened his mouth—what then? If he didn't shut it up powerful quick, he'd lose a lie, every time. That’s the kind of a bug Henry was; and if we’d ’a’ had him along ’stead of our kings, he’d ’a’ fooled that town a heap worse than ourn done.
