For me, a nonnative English speaker, the relation between Slovenian/Slovak/Russian videt’ and to wit/witness appeared to be a big surprise. So, I have decided to check another word that seems pretty old to me – gl’adEt’ (to look at). Well, now I know where Irish glen in Glenlivet, Glenfiddich and Glenmorangie comes from. But I will need to buy a bottle of each one to double check my speculations on why the Internet claims these two (gl’adet’ and glenn) are related. Linguistics turns to be more and more pleasant…
