- enormous
- 1530s, from L. enormis "irregular, extraordinary, very large," from ex- "out of" + norma "rule, norm" (see norm), with Eng. -ous substituted for L. -is. Meaning "extraordinary in size" is attested from 1540s; original sense of "outrageous" is more clearly preserved in enormity. Related: Enormously.
