Etymology

Origin of malefactor

1400–50; late Middle English malefactour < Latin malefactor, equivalent to malefac ( ere ) to act wickedly, do an evil deed ( see male-, fact) + -tor -tor


Explanation

A malefactor has done something illegal and has been or will be convicted, such as the malefactor who was videotaped stealing money from a cash register. To correctly pronounce malefactor, remember that the first syllable, mal rhymes with pal. A malefactor, however, is no friend you should have. Mal- comes from Latin and means "bad, evil," and facere means "to perform." A malefactor performs evil acts, or to put it a little less dramatically, does really bad things.
