heresy

nounPronunciation: /ˈher.ə.si/

In Portuguese: heresia

What does “heresy” mean?

A belief or opinion that goes against the established doctrine of a religion or, by extension, against what a group holds as unquestionable.

Etymology

From Middle English heresie, from Old French heresie, from Latin haeresis, from Greek hairesis, "a taking, a choice", and then "a school of thought", a noun of the verb haireisthai, "to take for oneself, to choose". In Greek the word was neutral and named philosophical schools. Christian writers gave it the sense of a doctrine chosen against the teaching of the Church, and from there came the general sense of an opinion opposed to what a group holds to be beyond question.

Usage note
