Origin of deformity
1350–1400; Middle English deformite < Old French < Latin dēfōrmitās, equivalent to dēfōrm ( is ) deform 2 + -itās -ity
Explanation
A deformity happens when a body part is misshapen. A deformity can also be a change for the worse in something's appearance. A two-headed kitten has a deformity. Usually a deformity is the result of an accident or a genetic defect. Although most people want to avoid deformities, in the novel Geek Love by Katherine Dunn (1989), the mother of a circus family takes drugs while she’s pregnant, hoping to cause deformities in her children. She succeeds with her son Arturo, who has flippers instead of arms and legs. In his world, people with regular arms and legs have the deformity.
