For example, if you pronounce the word 문리, the ㄴ turned into ㄹ because it is put right before ㄹ. However, the rule of the pronunciation of ㄹ is:
(according to a Reddit page)
ㄹ has two different pronunciations, depending on it's position.
- between vowels , R - However, unlike English 'r' which is pronounced with the tip of the tongue curled backwards, Korean is pronounced with the tip of the tongue flicking quickly against the dental ridge.
Example: 노래, ㄹ is between ㅗ and ㅐ which are vowels, and your word, 사랑
- in other positions , L - In Korean it is pronounced with the tongue touching against the dental ridge just behind the teeth as in the English word lap
Example: 몰라 ,first ㄹ is between ㅗ and ㄹ which are a vowel and a consonant, secondㄹ is between ㄹ and ㅏ which are a consonant and a vowel
But the word then has two Ls. So the pronunciation is like "molli". But then what is the difference between the singe L and double L?
