From īra + -ātus, later construed as the perfect active participle of īrāscor, which arose from it by back-formation.
īrātus (feminine īrāta, neuter īrātum, comparative īrātior, superlative īrātissimus); first/second-declension participle
- angry, irate, angered, enraged, furious, wrathful
- 4th century, St Jerome, Vulgate, Tobit 2:22
- ad haec uxor eius irata respondit manifeste vana facta est spes tua et elemosynae tuae modo paruerunt (At these words his wife being angry answered: It is evident the hope is come to nothing, and thy alms now appear.)
