Korean has separate phonemes for "r" and "l":
* "r" (ㄹ) is a liquid consonant pronounced similar to the English "r" in "red" or the "l" in "love" (but not as strong as the English "l").
* "l" (ㄹ) is also a liquid consonant and is pronounced very similarly to the "r" phoneme, so it's often described as a "flap" sound.
The distinction between "r" and "l" is often subtle and dependent on the surrounding sounds, making it difficult for some non-native speakers to differentiate them.
Therefore, there's no "r L" phoneme in Korean; instead, there are distinct "r" and "l" sounds.
