violador
/bjolaˈdoɾ/ · B2 · adj
rapist
violador = violar (to violate, break a rule or body) + -dor (one who does)
Violador comes from violar, which looks like English violate, plus the suffix -dor, like English -er or -or. So it means one who violates. As an adjective it means violating; as a noun it names an offender who commits sexual assault.
