accusative singular neuter of somanassa (noun)
Analysis. saṁ + manas + a: sam- (together) + manas (mind) + -a (nominal suffix); literally 'mind brought together', hence unified, bright, pleased
Etymology. sam- + manas: the prefix sam- (together, completely; cognate with English 'same', Latin con-) added to manas (mind, from the root √man 'to think', cognate with English 'mind', Latin mens). The spatial sense of sam- (things brought into one) carries the abstract meaning of mental unification into joy.
