Notes: Cf. also HU: Hurr. edǝ 'body, thing', Ur. edi- 'thing' (see Diakonoff-Starostin 1986, 26). It is not quite clear which meaning is original - 'thing' or 'what', because both are rather widely reflected.
We should also mention a quite isolated form: Lak. ta 'when', which has an irregular devoiced t-, but possibly reflects the same EC root.
