dative for possession will be easy for korean or japanese speakers. these altai languages say like "to me is a house" when they mean "i have a house".
and greek has similar phonological phenomena as korean.
leleip+menos -> leleimmenos
sun+logos -> sullogos
many koreans pronounce henry as helly(no distinction btn r and l) because of the consonant assimilation but that's an advantage when learning greek. and word sequence in a sentence somewaht resembles that of korean. as in
oikos moi esti
"[jib-i: house] [na-e-ge: to me] [itta:is]"
so i cannot understand why they dont teach greek in the school in korea.
sorry for random complaint
