-ate

1

a suffix occurring in loanwords from Latin, its English distribution paralleling that of Latin. The form originated as a suffix added to a-stem verbs to form adjectives (separate). The resulting form could also be used independently as a noun (advocate) and came to be used as a stem on which a verb could be formed (separate; advocate; agitate). In English the use as a verbal suffix has been extended to stems of non-Latin origin: calibrate; acierate.
