I just started learning the Korean language and want to build strong pillars from beginning. That means getting the pronounciation right. Can someone write down all the rules for each letter in the alphabet and how the sound changes ( if it does) and when. Like if a consonant sounds different if it's in the beginning or between vowels or at the end. I know someone already posted that detailed information on this site on the "ㄹ" letter but I can't find the rest of them.

thank you so much
