ˁadu - yet (WTS 482)

PWS
*ˁād- - (he is) still (Kogan 2015: 76–77, 105)
likely candidate for a PWS lexical innovation, ultimately connected with the verbal root *ˁwd ‘to turn’ It is hard to avoid thinking, however, that the functional equivalent of *ˁād- in Akkadian, namely adīni ‘until now; not yet’, has something to do with it also in terms of etymology (Kogan 2015: 76)
