[enor.mi.ty] n, pl -ties (15c) 1: an outrageous, improper, vicious, or immoral act "the enormities of state power --Susan Sontag" "other enormities too juvenile to mention --Richard Freedman"

4: a quality of momentous importance usage 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 usu. suggests something so large as to seem overwhelming "no intermediate zone of study. Either the enormity of the desert or the sight of a tiny flower --Paul Theroux" "the enormity of the task of teachers in slum schools --J. B. Conant" and may even be used to suggest both great size and deviation from morality "the enormity of existing stockpiles of atomic weapons --New Republic". It can also emphasize the momentousness of what has happened "the sombre enormity of the Russian Revolution --George Steiner" or of its consequences "perceived as no one in the family could the enormity of the misfortune --E. L. Doctorow".
