1. When ㄹ is placed at the beginning of the word, it's pronounced as R

- 라디오 : Radio

- 라면 : Ramyeon 

2. When placed at the end, it's pronounced as L 

- 신발 : Shinbal 

- 딸: Ddal

3. In the middle of the word, if it is followed by a vowel, pronounced as R 

- 따라하다 : Ddarahada

-- 팔아요 : Parayo

4. *f followed by a consonant or another ㄹ, read as L 

- 달라 : Dalla 

5. If it comes after ㅇ, it's read as N 

- 승리 : Seungni

I think you will realize that all R, L sounds used in English don't match exactly those in korean.

Actually, that's the reason why korean people normally have a difficulty to pronounce R,L sounds in English.

Yeah, We korean can understand what you said if you pronounce word 'ㄹ' in your way (R,L).

Then you don't have to pratice pronounciation because it won't make a bit of difference :)

'ㄹ' is totally different sound

normally just use ㄹ for all the L and R

ex) radio = 라디오

     rule = 룰

     lemon = 레몬

     locker, rocker = 락커

yeah, cannot really pronounce english with korean letters

Here is a Youtuber that helps with the sounds of the Korean alphabet SungHeeReginaHong.
