[caffeine + -ate1 + -ed2]-ate is a suffix occurring in loanwords from Latin, its English distribution parallelingthat 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); -ed is a suffix forming the past participle of weak verbs (he had crossed the river), and of participial adjectives indicating a condition or quality resulting fromthe action of the verb (inflated balloons). Other words that use the affix -ed include: connected, integrated, saturated, sheltered, unsettled
