ʸhéẓ̂ar - to be green (LS 420; CSOL I 695; CSOL II 629; Naumkin et al. 2015a:92)

Proto-MSA
*šṣ̂r - to be green (Kogan 2015:542)
“Proto-MSA *šṣ̂r ‘to be green’ comes close to Arb. ḫḍr with the same meaning (Lane 754), but the extremely problematic correspondence *š vs. *ḫ makes a straightforward acceptance of this equation rather unappealing (see further Bittner 1915b:67, Bulakh 2004:276‒277). There is no trace of PS *wrḳ ‘to be green’ in MSA.” (Kogan 2015:542)
