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)
