Enormity vs. Enormousness: Usage Guide

Enormity, some people insist, is improperly used to denote large size. They insist on enormousness for this meaning, and would limit enormity to the meaning "great wickedness." Those who urge such a limitation may not recognize the subtlety with which enormity is actually used. It regularly denotes a considerable departure from the expected or normal. they awakened; they sat up; and then the enormity of their situation burst upon them. "How did the fire start?" — John Steinbeck When used to denote large size, either literal or figurative, it usually suggests something so large as to seem overwhelming no intermediate zone of study.

Did You Know?

Although enormity has been used since the late 1700s to denote large size, this usage continues to be disparaged by various language commentators who argue that enormity should be reserved for senses related to "great wickedness." It is enormousness, they insist (a hefty and considerably less common word), that should be used in reference to great size, despite the fact that, like enormity, it too originally was used to denote wickedness or divergence from accepted moral standards. For better or worse, this proscription has been widely ignored by many English speakers, including professional writers. However one chooses to use them, enormity and enormous can both be traced back to the Latin enormis, from the prefix e- ("out of") and norma ("rule," "pattern," or "carpenter's square").
