sandhi contraction: na + eva + assa
Analysis. na (negation) + eva (emphatic particle, 'even') + assa (optative of atthi, 'would be'). The three words fuse in sandhi: na + eva → neve, then neve + assa → nevassa. Doctrinal use: common in denying even the possibility of a state or attainment.
Etymology. na is the simple negation (cognate with English 'no', Latin ne); eva is an emphatic particle meaning 'even' or 'just' (akin to Sanskrit eva); assa is the optative of atthi 'to be' (cognate with English 'is', Latin est, Greek esti).
