I am a korean beginner and learning korean. I have learnt hanguel characters, some vocab and some pronunciation too (batchim) but there is a confusion. When we know that (ㄹ) is pronounced as R or L like I'm really confused. in water, its Mul with a bit sound of r. but in many words it sometimes r sometimes l and its not understandable to me. Kindly help
