ㄹ irregular verbs
Verbs and adjectives whose stem ends with a ㄹ 받침 are irregular. Some examples of include 알다, 살다, 열다 and 팔다. These verbs/adjectives don't follow normal conjugation rules required for 받침 containing stems, and instead follow the conjugation rules of non 받침 verbs. Also if followed by ㄴ,ㅂ,ㅅ, then the ㄹ in the stem disappears.
Explanation
Normally verb/adjectives whose stem has a 받침 follows a certain type of rule to conjugate it with a grammar pattern. If you notice in this wiki and many other text books, there is often a (으) in grammar patterns, some examples include A/V + (으)면, A/V + (으)니까. So for example, the pattern A/V + (으)면 has two rules, if it has a 받침 at the end of the stem, add 으면 to the stem, otherwise just add 면 to the stem. In the case that ㄹ is 받침, it follows the grammar patterns as the stems with no 받침.
As stated previously, these verbs/adjective stems follow the same conjugation rules as stems without a 받침.So if it is followed by ㄴ,ㅂ,ㅅ, then the ㄹ disappears. For example 팔다 in the grammar form V + (으)세요 becomes 파세요, NOT 팔세요.
Step by Step Example 1
Pattern | Case | |
---|---|---|
Rule 1: | 면 | If there is no 받침 |
Rule 2: | 으면 | If there is a 받침 |
Step # | 가다 (to go) | 먹다 (to eat) | 알다 (to know) |
---|---|---|---|
Step 1: Does it have a 받침 at the end of stem? | No | Yes, the 받침 is ㄱ | Yes, the 받침 is ㄹ (special case) |
Step 2: Find proper conjugation rule | Use rule 1: A/V + 면 |
Use rule 2: A/V + 으면 |
It is a ㄹ 받침 (irregular) and we treat it like there is no 받침, so we must use rule 1 instead of rule 2, so A/V + 면 |
Step 3: Apply the conjugation rule | 가면 | 먹으면 | 알면 |
Step by Step Example 2
Pattern | Case | |
---|---|---|
Rule 1: | 니까 | If there is no 받침 |
Rule 2: | 으니까 | If there is a 받침 |
Step # | 가다 (to go) | 먹다 (to eat) | 알다 (to know) |
---|---|---|---|
Step 1: Does it have a 받침 at the end of stem? | No | Yes, the 받침 is ㄱ | Yes, the 받침 is ㄹ (special case) |
Step 2: Find proper conjugation rule | Use rule 1: A/V + 니까 |
Use rule 2: A/V + 으니까 |
It is a ㄹ 받침 (irregular) and we treat it like there is no 받침, so we must use rule 1 instead of rule 2, so A/V + 니까 |
Step 3: Apply the conjugation rule | 가니까 | 먹으니까 | 알니까 |
Step 4: Fix conflict | No conflict(regular verb) | No conflict(regular verb) | The ㄹ disappears and it becomes 아니까 because there was a conflict between the ㄹ 받침 and ㄴ in the previous step. |
