*aisk- 'bright, shining'

Looking about any connection of the Illyrian and the Albanian
languages, I find interesting the word *aiska: `bright, shining'
(Pokorny, 16-17), that seems yields Albanian <eshkë> `amadou,
touchwood' from *aiska: < *H2eisk-eH2, used almost in syntagm <eshkë
e unur/uror> `touchwood and steel - a piece of stone hard like steel,
through which the touchwood sparkles' and Alb. verb <rreshk> `to
brown under the sun, heat', deverbativ <rreshkatore> `toast', as e
prefixed verb rr-eshk.
*ai > e and *sk > shk, as a: > ë (at the end of the words) are
regular outcomes in Albanian.
Cogantes are OlChSl. <iskra> `spark', <jasan> `clear', lit.
is^kus `clear', etc.
According to Miklosich, Meyer, Meyer-Lübke, Haarmann and Orel it is
borrowed from Lat. e:sca that I guess is hard to be believed.
