Korean irregular verb ㄹ summary

when the final consonant ‘ㄹ’ in the stem meets the individual consonant ‘ㄹ’ in the ending the final consonant ‘ㄹ’ is omitted and the individual consonant ‘ㄹ’ becomes the final consonant. So, when ‘살다’ meets ‘ㄹ까요’, it becomes ‘살까요.’

when the final consonant ‘ㄹ’ in the stem meets a letter which begins with ‘ㄹ’ the final consonant ‘ㄹ’ remains the same. So, when ‘살다’ meets ‘려고 하다’, it becomes ‘살려고 하다.’ The final consonant ‘ㄹ’ remains.

Now, let’s find out when the final consonant ‘ㄹ’ in the stem meets the adjective/verb ending that begins with the vowel ‘으.’ These are the endings we’ve learned. What do they have in common?

When the stem has the final consonant, they all contain the vowel ‘으.’ Basically, when an adjective/verb stem has the final consonant, ‘으세요, 을까요, 을 거예요, 으려고 하다’ are used. And they all start with ‘으.’

On the other hand, when an adjective/verb stem does not have the final consonant, ‘세요, ㄹ까요, ㄹ 거예요, 려고 하다’ are used which does not have ‘으.’ But, when ‘살다’ that has the final consonant ‘ㄹ’ is combined with the endings,It is combined with the endings which do not have ‘으’.Why is it? Let’s look at them together.

When the final consonant ‘ㄹ’ in the stem meets the endings that begin with ‘으,’ ‘으’ is omitted. And the final consonant ‘ㄹ’ remains. Let’s look at some examples.

‘살다’ + ‘ㄹ 거예요.’

In this time, ‘살다’ meets ‘ㄹ 거예요.’

First, remove ‘다’ from ‘살다, and there is the final consonant ‘ㄹ’ in the stem. When the ending that begins with the individual consonant ‘ㄹ’ is added after that, ‘ㄹ’ is omitted from ‘살 ㄹ 거예요.’

The individual consonant ‘ㄹ’ in the ending is used as the final consonant. So, it becomes ‘살 거예요’.

 ‘살다’ + ‘ㄹ까요.

’when the verb ‘살다’ meets ‘ㄹ까요.’

First, remove ‘다’ from ‘살다, and there is the final consonant ‘ㄹ’ in the stem. When the ending that begins with the individual consonant ‘ㄹ’ is added after that the final consonant ‘ㄹ’ in the stem is omitted from ‘살ㄹ까요.’ And the individual consonant ‘ㄹ’ is used as the final consonant. So, it becomes ‘살까요?’

‘살다’ +‘려고 하다’

Then, how about when ‘살다’ meets ‘려고 하다’?

Firstly, remove ‘다’ from ‘살다, and there is the final consonant ‘ㄹ’ in the stem. Then the letter ‘려’ is added after that. ‘려’ is different from the individual consonant ‘ㄹ.’ ‘려’ is the letter from the combination between ㄹ and ㅕ. In this case, the final consonant ‘ㄹ’ is not omitted. So, it becomes ‘살려고 하다.’

We’re going to look at the case when 살다’ meets ‘을 거예요.’

Basically, as 살다 has the final consonant ‘ㄹ’, it is correct to add ‘을 거예요.’ But, there is the final consonant ‘ㄹ’ after removing ‘다’ from ‘살다.’ And the vowel ‘으’ is added after that. In this case, the vowel ‘으’ is omitted. So, ‘ㄹ 거예요’ is added after ‘살.’

Moreover, here again, the final consonant ‘ㄹ’ in the stem meets the individual consonant ‘ㄹ’ in the ending. We’ve just looked at it. In the case, the final consonant ‘ㄹ’ is omitted. And the individual consonant ‘ㄹ’ becomes the final consonant. So it becomes ‘살 거예요.’ Let’s look at some more examples.

살다+ 을 거예요

We’re going to look at the case when 살다’ meets ‘을 거예요.’

Basically, as 살다 has the final consonant ‘ㄹ’, it is correct to add ‘을 거예요.’ But, there is the final consonant ‘ㄹ’ after removing ‘다’ from ‘살다.’ And the vowel ‘으’ is added after that. In this case, the vowel ‘으’ is omitted. So, ‘ㄹ 거예요’ is added after ‘살.’

Moreover, here again, the final consonant ‘ㄹ’ in the stem meets the individual consonant ‘ㄹ’ in the ending. We’ve just looked at it. In the case, the final consonant ‘ㄹ’ is omitted. And the individual consonant ‘ㄹ’ becomes the final consonant. So it becomes ‘살 거예요.’ Let’s look at some more examples.

살다 +으세요?

How would it become when 살다 meets 으세요? Remove ‘다’. The final consonant ‘ㄹ’ meets the vowel ‘으’. Then, ‘으’ is omitted. It becomes ‘살세요.’

Here again, the final consonant ‘ㄹ’ meets the ending that begins with ‘ㅅ’. Then, the final consonant ‘ㄹ’ is omitted, and it becomes ‘사세요.’ Here is another example.

살다 + 읍니다

What would it become when 살다 meets 읍니다? Remove ‘다’, then the final consonant ‘ㄹ’ meets the vowel ‘으.’ Then, ‘으’ is omitted. It becomes ‘살ㅂ니다.’

Here again, the final consonant ‘ㄹ’ meets the ending that begins with ‘ㅂ’ Then, the final consonant ‘ㄹ’ is omitted. And ‘ㅂ’ is used as the final consonant, it becomes ‘삽니다.’

‘살다’ + ‘으려고 하다.’

Lastly, what would it become when ‘살다’ meets ‘으려고 하다.’?

Remove ‘다’, then the final consonant ‘ㄹ’ meets the vowel ‘으.’ Then, the final consonant ‘ㄹ’ is omitted. It becomes ‘살려고 하다.’ So, when the final consonant ‘ㄹ’ in the stem meets the vowel ‘으,’ ‘으’ is omitted. And the endings such as ‘세요, ㅂ니다, 려고 하다’ are added directly after the stem.
