To consume; to use up or eat (archaic or rare variant of 'consume').
From Latin consummare, related to consumere (to consume). This variant spelling and form survives mainly in historical texts and has largely been replaced by 'consume.'
This archaic form shows how English simplified its Latin-derived verbs—'consumate' competed with 'consume' and lost, leaving behind only 'consummate' (meaning perfect) as a surviving relative.
