Zway

atä - you (masc. sg.) (EDG 102)

The loss of -n- (apparently, resulting from assimilation with the further reduction *ˀanta > *ˀatta > atä) is unusual for EthS and remains to be explained (Bulakh–Kogan 2013b:96). Compare Tna. ˀanta with its variant ˀatta.

PS
*ˀantā̆ - thou (masc. sg.) (CDG 32, Kogan 2009:66, Kogan 2015: 35)
CDG 32: ‘you’
