Enormity vs. Enormousness: Usage Guide

The original meanings that enormity carried related to great wickedness, and some assert that enormity should today only be used with such meanings, and that enormousness is the proper word to use to mean "large size." Despite these claims, enormity frequently refers to large size, either literal or figurative, though it usually suggests something so large as to seem overwhelming.

the enormity of the task at hand

Enormity can also refer to a shocking, evil, or immoral act

the enormities of war

and it can also suggest both great size and deviation from morality.

The enormity of existing stockpiles of atomic weapons … New Republic

Enormity can also emphasize the momentousness of what has happened or of its consequences.

not fully grasping the enormity of their decision

It's worth noting that enormousness formerly shared the disagreeable meanings that enormity still carries, but it now means merely "large size."

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").
