μούχλα

Etymology
From, borrowed from (?)   / (“pus, water under a blister”; in the usually attested Eastern language forms instead not actually recorded as “mould”, apparently then transferred from an idea of “damaging liquid”),    when also around the same time 🇨🇬 forms the compound ,  as otherwise the present term would have to be from  and the 🇨🇬 term  parallelly from ; prompt to conjecture native etymologies, Indo-Europeanists sport the leading opinion even that the Bulgarian and Macedonian terms in the descendants section below would rather hail from.

Noun

 * 1)  mould, mold
