[Grammar] ㄹ 탈락 : ㄹ drop

ㄹ 탈락 : ㄹ drop

You already know, vowel endings which start with -(으) or -(스) take place after a verb/adjective which ends with a final consonant. For example,

받+(스)ㅂ니다 -> 받습니다

읽+(으)러 -> 읽으러

닦+(으)면 -> 닦으면

However, when (으) or (스) is followed by ㄹfinal consonant, (으) or (스) drops.  For example,

1) 살+(으)러 -> 살러

2) 멀+(으)면 -> 멀면

*3) 울+(스)니다 -> 웁니다

*4) 울+(으)까 -> 우니까

*5) 울+(으)어요-> 우셨어요

*6) 멀+(으) -> 먼

*7) 살+ -> 사는

You can see that there is no (으) in 1) and 2).  If you look closely, there are more changes in 3)~7).  After (으) or (스) drops, if there is ㄴ / ㅂ / ㅅ, ㄹfinal consonant drops.  The table below will help you understand the process.
