why= wae. (way)
what are you doin? mwo-hae? (mwo-hey)
what is your name? i-reum-i mwo-e-yo? (ee-reum-ee-mwo-eh-yo)

When I first learned how to speak Korean I could only read romanji, so I can translate Korean directly from Hangul-Romanji. The ones in bracets are SOMEWHAT how you pronounce them.. It's hard to translate the exact sounds into English ^^;
