masc dat sg of sammāsambuddha (noun); masc gen sg of sammāsambuddha (noun)
Analysis. sammā (rightly, perfectly) + sambuddha (fully awakened); sambuddha itself breaks down as sam- (together, completely) + buddha (awakened, from √budh), so the full sense is 'completely and rightly awakened together with all truth'
Etymology. sam + buddha from √budh 'to awaken, understand'; sam- is cognate with English 'same' and Latin 'simul' (together); buddha is cognate with English 'bode' (archaic, 'to await, know') and German 'bieten' — the root sense of 'waking to knowledge' — Sanskrit buddhi; the prefix sammā- adds the sense of 'in the right way, perfectly'
