o===oo

오 o as in "go"? Well, I normally pronounce it as in "law"... But sometimes they both are quite similar. I read (I don't remember where) that in spoken korean they sometimes tend to have the same sound...

yes that's right 오 as o 우 as u or oo ^^

오 as “o” in “go” 우 as “u” in “flute” I’m not a Korean speaker, but I guess that should be right.
