First word Goroh attributes to Romanian/Moldovanian, given that this word is not listed on wiktionary it is definitely dialectal restricted and has no known etymology. It is very likely a Dacian Carpathian word borrowed into Romanian not the other way around.
byh-uvaty is clearly related to an entry from Romanian-Hutsul dictionary where the definition was more accurate as the author listed to plan. The author of the Ukranian dicitonary is focusing on the intenion but is not familiar with meaning of the root word, te
bëj/
bëhet is used in common Albanain talk when to parents relatives are trying to match couples for marriage, it simply means to become, and of course there is desire behind it, but that's not the root meaning behind the word. Ukranian linguists are missing out. The Albanoid root explanation is re-enforced by the secondary semantic shift in meaning changeable/sudden weather, which in turn strengthens my hypothesis overall as Hutsul words are not one off cognate lookalikes, the semantic drift in meaning mirrors Albanian forms.
Byz/biz is attributed as a loan from Hngarian: bíz. But the Hungarian word has no etymology hence no explanation, and the distribution is clearly Carpathian-Beskides.

I am certain that similarity to Albanian bes was never noticed because of the taboo of the alleged Illyric roots of Albanian language, and likely a hostile environment that has existed and still exists in academia on the topic.
