Hello, and thank you for your suggestions, User:AdiJapan.

I suppose you're right about "Bască" (though the word "[Basque]" has no connection with Latin, it is more likely a later addition to the Romanian language  I can't imagine a pilleati wearing one p ) and you might be right about "gîdel" also. 

For the other two though, "adămană" and "dezgauc", I heard them used with the indicated meanings (the latter as a verb, as matter of fact). Of course, that doesn't necessary mean that those were the original meanings.

Indeed, we do need a language specialist here (I'm no such creature, unfortunately) but until then, I decided that nowadays meaning is better than no meaning for those words.. and I stand corrected.
