indeclinable (sandhi form: tu + eva)
Analysis. tu + eva: 'tu' (conjunctive particle, 'but, however') + 'eva' (emphatic particle, 'even, just'); the combination marks contrast or emphasis, often introducing or closing direct speech or emphatic assertions.
Etymology. tu is a conjunction of uncertain origin; eva derives from the pronominal root with sense of 'being' or 'thisness', used as an intensifier across Indo-European languages (cognate with English 'ever', Latin 'et' 'and', Greek 'e' 'or').
