The second way to use the pattern ‘-지 않다‘. This pattern directly followes by verbs or adjectives. So, negation formed by ‘‘ is called ‘short type negation’, and the Negation by ‘-지 않다 is ‘long type negation’.There is no difference in meaning between the form ‘ + verb/adjective’ and the form ‘verb/adjective + –지 않아요‘.

[Easy Korean] Unit 14 ~을 수 있어요/없어요 : can (do) / can not (do)

1. ~을(ㄹ) 수 있어요/없어요 : can (do) / can not (do)

~을(ㄹ) 수 있어요/없어요 is used to express ability/possibility or inability/impossibility.

~을(ㄹ) 수 있어요 indicates ability, capability, possibility or permission. ~을(ㄹ) 수 없어요 is the negative form.

~을(ㄹ) 수 있어요/없어요 is used with verbs. If the verb stem ends in a consonant, ‘~을 수 있어요/없어요’ is added, and if the verb stem ends in a vowel, ‘~ㄹ 수 있어요/없어요’ is added.

*** Note!!  What’s the difference?

When ‘~을(ㄹ) 수 있어요/없어요’ is used to express the ability to do something, ‘~을(ㄹ) 수 있어요/없어요’ has almost the same meaning as ‘~을(ㄹ) 줄 알아요/몰라요’, and therefore they can be interchanged.

E.g. 앤디 씨는 한국어를 할 수 있어요. = 앤디 씨는 한국어를 할 줄 알아요.
Andy can speak Korean.        Andy knows how to speak Korean.

However, while ‘~을(ㄹ) 수 있어요/없어요’ can also be used to express the possibility of doing something, ‘ ~을(ㄹ) 줄 알아요/몰라요’ cannot be.

~을(ㄹ) 줄 알아요/몰라요 expresses whether one knows how or has the ability to do something.
나는 딸기잼을 만들 줄 몰라요.
I don’t know how to make strawberry jam.

~수(ㄹ) 있어요/없어요 used not only to express the ability to do something but also whether a situation permits somethings to be done.
나는 딸기잼을 만들 수 없어요.
ⓐ I don’t know how to make strawberry jam.
ⓑ I know how to make strawberry jam, but for some reason(such as a lack of strawberries,) I can’t make it right now.

E.g.  저는 한국어를 할 수 있어요(O) I can speak Korean.
저는 한국어를 할 줄 알아요(O) I know how to speak Korean.

내일 영화를 볼 수 있어요.(O) I can/It’s possible to see a movie tomorrow.
