past participle (nominative singular masculine); the surface form abhisambuddhoti adds the quotative particle iti
Analysis. abhi-sam-buddha + iti: abhi (toward, bearing down) + sam (together, completely) + budd(h)- (awoken, past participle of √budh 'to awake, realize') + -a (adjective ending) + iti (quotative particle, 'thus, saying'). The two prefixes stack to show entire, complete realization: sam- brings the action together into unity, and abhi- bears down on it with intensity.
Etymology. From √budh 'to awake, wake up, realize' (Sanskrit bodhati; English bud, to swell forth; German Boden ground—all share the sense of emergence and growth), prefixed by abhi- (toward, bearing down, like Latin ob- in observe) and sam- (together, completely, like Latin con- in cognoscere 'to know together'). The root's basic image of awakening becomes, through these prefixes, the canonical term for Buddha's enlightenment: not merely waking but the gathering together of all wisdom into one supreme moment of clarity.
