Etymology

Origin of inimical

First recorded in 1635–45; from Latin inimīc(us) “unfriendly, hostile” ( see enemy) + -al 1

Explanation

Censorship is inimical to freedom. So, most teenagers would argue, are curfews. To be inimical is to be harmful, antagonistic, or opposed to something. Inimical comes from the Latin word inimicus, meaning "enemy." It suggests acting like someone's enemy — being adverse, damaging, or downright hostile. It can refer to anything from emotions and actions to public policy. The U.S. government might declare that another nation's actions are inimical to national security — and your mom might declare that eating a dozen doughnuts every morning is inimical to your health. Be careful not to mix up inimical with inimitable, which means too good to be copied.
