-а́тор • (-átor)

1. Suffix used to form agent nouns (both animate and inanimate) from verbs in -и́ровать (-írovatʹ), -ирова́ть (-irovátʹ) and -ова́ть (-ovátʹ): -ator, -er

   ‎декори́ровать (dekorírovatʹ, “to decorate”) + ‎-а́тор (-átor) → ‎декора́тор (dekorátor, “decorator”)

   ‎эксплуати́ровать (ekspluatírovatʹ, “to exploit”) + ‎-а́тор (-átor) → ‎эксплуата́тор (ekspluatátor, “exploiter”)

   ‎экзаменова́ть (ekzamenovátʹ, “to test (with an exam)”) + ‎-а́тор (-átor) → ‎экзамена́тор (ekzamenátor, “examiner, tester (someone who administers an exam)”)

• This suffix is added to verbs in -и́ровать (-írovatʹ), -ирова́ть (-irovátʹ) and -ова́ть (-ovátʹ), and replaces these suffixes. Most (but not all) such verbs are derived from foreign words, especially words of Latin origin.
