indeclinable + eva
Analysis. appakasirena + eva; appakasirena is appa + kasirena. appa (little, small) + kasirena (with difficulty, instrumental singular of kasira 'difficult'). The sense is 'with little difficulty', hence 'easily'. eva is the emphatic particle 'indeed, just'.
Etymology. appa < *(s)p-: compare Sanskrit alpa 'small', Greek spanos 'sparse'. kasira is of uncertain origin but related to the semantic field of hardship; the construction kasirena literally means 'with difficulty' (instrumental of kasira), so appakasirena inverts this to mean 'with-little-difficulty'. eva is an old particle cognate with Sanskrit eva 'just, indeed'.
