In my best understanding, 의 can be read like [의] or[에]. ( [ ... ] means the actual pronunciation.) Of course, [의] is the original sound and should be read so in common words such as 의사(doctor), 의자(chair). When 의 means particle "of", it's also allowed to read like [에]. Example: 한국의 집[한구게 집 or 한구긔 집] 나의 means "my", so it could be pronounced like [나의or 나에]. Additionally, 나의is often abbreviated to 내. That's what I was taught. Correction is welcome:)

no, Hikari, that's not right. it doesn't sound like Naw-yeh. Korean characters can't be same pronounciation as English at all. so please keep that in mind. and please read following: inside of [ ] are phonetic signs, not an alphabet. all the korean characters have fixed sounds for each. so you can pronounce same as you see always. 나의(which means 'my') 나=ㄴ+아 =ok in that case korean 'ㄴ(니은)' sounds similar as [n] and 'ㅏ[아]' sounds like 'ah[a]'. so if we express this for American English it could be nah but a bit different. but very closer. Every language has different sounds, we all know but we can follow similar pronounciation. so it could be 'nah', if we want to say in american english pronounciation. 의=으+이 으 is very different sound from american english. how can you pronounce this? well ok follow this. Make your mouth shape same as when you pronounce 'e[i]'. and then with that shape, try to pronounce 'oo[u]'. that's more like 으 and how the heck is '의' then? well when you say '으' and then you finish with 'e[i]' very quickly. then that sound is '의' can you get it? if you dont, ask again, I will find out the way you can understand. ok? :) hope it could be helpful. have a great nite. :)

Naui ? Na-i means 'age' 나이 Naw-yeh ? Na-ye-yo or Na-ya means 'It is me' 'here I am' 나에요 , 나야
