Notes: Cf. also Hurr. ašχi 'skin' (regularly < *arci, see Diakonoff-Starostin 1986, 47). An interesting common NC root. The original meaning is obviously "skin" > "surface, exterior, color" > (change of color = ) "anger, anxiety". The whole spectre of meanings is present both in EC and in WC languages.
See Abdokov 1983, 76 (Shakhdagh-WC; all other EC forms cited by the author do not belong here).
