In Serbian the word "ruka" means "hand, arm". This is Slavic only word, borrowed by Latvians and Lithuanians. The expression "iz ruke" means "from the hand". You take something that someone is giving you from his hand. The expression "iz ruku" means "from the hands". You take something that someone is giving you from his hands. To give something, you need to "let go of it", "let it out of your hand" which in Serbian is "iz ruke" = from the hand, "iz ruku" = from the hands, or if you are an "uneducated peasant" you would say "iz rukama" = from the hands
But today while browsing the Sumerian dictionary, as you would :) , I came across this: Sumerian: ISRUK = Gave (he gave) ISRUKAM = Gave (he gave to me)
I also found this word:
NADANU = Give, Give (to pay)
Once the thing is given, in Serbian it is "dan (M), dana (F), dano (N)" meaning "given".
Now the Slavic verb "dati" meaning "to give" comes from Indoeuropean root "deh₃-". But how many non Slavic languages have word "na" with the above meaning?
And what the hell are these words doing in Sumerian???
Any plausible explanation anyone?
