Irish: Scot old name for an Irishman. Old Irish were predominantly cattle herders and the whole society was organized around cattle and sheep. Cattle was the main property of any person and determined how wealthy someone was.
Serbian: skot - cattle but also litter (animal young); skotan (pregnant animal with litter). Veles, Volos was known as "Skotiji bog" meaning the cattle god. Proto Germanic "*skattaz" meaning cattle, kine and by extension owndom, wealth, goods, hoard, treasure, money, comes from Slavic skot meaning cattle as cattle was the original wealth. Skot also means "evil and merciless" person...
Was "Scoti" the old name given to the Irish given to them by their neighbors with the meaning Scoti = "cattle herders" who were also cattle raiders hence not very nice "evil and merciless" people? Or maybe the name did come from the Princess Scota...
Irish: mál - Prince, chief, noble
Serbian: mal - cattle, wealth. The word mal with the meaning of wealth is also found in Turkic languages and in Arabic. I presume that the original meaning was cattle, and considering that the Arabic doesn't contain the meaning cattle I wonder where and how far back in the past does the origin of this word lies...
What do you think about this? Long period of mutual insulting between the Serbians (Slavs) and the Irish, or just Proto Indo European common words which somehow were forgotten by all the other Indoeuropeans? I did try to find these words in other Indoeuropean languages apart from Slavic and Celtic, and I specified other cognates where I could find them. I would appreciate any information about the cognates that I have missed, so that I can update my post. Because the number of these non Celtic and non Slavic cognates is so small, I would say that the first thing is much more likely. Celts and Slavs spent a lot of time insulting each other... :)
Particularly interesting are the words from the Irish language which are built using root blocks from Slavic languages. How did they end up in the Irish language?
