ㄹ 수 있다

Hello learners! Today, we're diving into a super useful Korean expression: ㄹ 수 있다. This phrase is your go-to for talking about ability or possibility. It's how you say 'can' or 'be able to' in Korean. Once you get the hang of it, you'll be able to express a lot more in your conversations.

§ What ㄹ 수 있다 Means

DEFINITION

Indicates ability or possibility; can, be able to.

At its core, ㄹ 수 있다 tells you that something is possible or that someone has the capability to do something. Think of it like the English 'can' or 'be able to'.

§ How to Use It with Verbs

The magic of ㄹ 수 있다 comes when you attach it to a verb stem. Here's how it works:

• If the verb stem ends in a vowel or the consonant 'ㄹ', you add -ㄹ 수 있다.
• If the verb stem ends in any other consonant, you add -을 수 있다.

§ Examples with Verbs

Let's look at some examples to make this clear. Pay attention to how the ending changes based on the verb stem.

Here, '하다' (to do/speak) becomes '할 수 있어요' because '하' ends in a vowel.

The verb '읽다' (to read) has a stem '읽' which ends in a consonant (ㄱ), so we add '을 수 있어요'.

For '운전하다' (to drive), the stem '운전하' ends in a vowel, so it's '운전할 수 없어요' for 'cannot drive'.

'만나다' (to meet) has a vowel ending, so it's '만날 수 있을까요'. Notice how '있다' can be conjugated to '있을까요' to form a question about possibility.

§ Don't Confuse with 'Can't Do'

While ㄹ 수 없다 is the direct opposite, there's another way to say 'cannot' which is '못'.

• 못 + Verb: This implies inability due to external circumstances or simply 'cannot'.
• ㄹ 수 없다: This often implies a lack of skill or internal ability.

Keep practicing these structures, and you'll be expressing abilities and possibilities like a pro in no time! Good luck with your studies!

§ What does -ㄹ 수 있다 mean?

Meaning

Indicates ability or possibility; can, be able to.

The core idea here is either that you have the ability to do something, or that something is possible to happen. It's a very versatile phrase.

§ How to Form -ㄹ 수 있다

The formation is pretty straightforward. You attach -ㄹ 수 있다 to the stem of a verb. Here's how it works:

• If the verb stem ends with a vowel or the consonant 'ㄹ' (e.g., 가다, 만들다), you attach -ㄹ 수 있다.
  • 가다 (to go) → 갈 수 있다 (can go)
  • 만들다 (to make) → 만들 수 있다 (can make)
• If the verb stem ends with any other consonant (e.g., 먹다, 읽다), you attach -을 수 있다.
  • 먹다 (to eat) → 먹을 수 있다 (can eat)
  • 읽다 (to read) → 읽을 수 있다 (can read)

§ Examples in Action

Let's look at some practical examples to see how -ㄹ 수 있다 is used in sentences.

Hint

I can speak Korean.

Hint

I can read this book by myself.

Hint

It might rain today (it's possible it will rain today).

Notice how it covers both personal ability and general possibility.

§ Negative Form: -ㄹ 수 없다

To say you cannot do something or that something is not possible, you simply replace 있다 with 없다.

• 저는 한국어를 말할 수 없어요. (I cannot speak Korean.)
• 이 책은 혼자서 읽을 수 없어요. (I cannot read this book by myself.)

§ Similar Words and When to Use -ㄹ 수 있다 vs. Alternatives

Korean has a few ways to express ability, and while they might seem similar, there are subtle differences. Let's look at a key one:

1. -ㄹ 수 있다 vs. -지 못하다

Both -ㄹ 수 없다 and -지 못하다 express inability, but they have slightly different nuances.

• -ㄹ 수 없다: This typically indicates that you cannot do something due to external circumstances, lack of opportunity, or because it's simply impossible. It often implies a physical or circumstantial limitation.
• -지 못하다: This often implies that you fail to do something, or that you don't have the skill or confidence to do it, despite possibly having the opportunity. It can sometimes carry a sense of regret or inability due to an internal factor.

In many casual situations, people use them interchangeably, but understanding the subtle difference can make your Korean sound more natural.

2. -ㄹ 줄 알다/모르다

This expression specifically refers to knowing how to do something. It's about skill or knowledge.

• -ㄹ 수 있다: Broader, means 'can' (ability or possibility).
• -ㄹ 줄 알다: Specifically means 'know how to' (skill/knowledge).

While both might translate to "I can play the piano," -ㄹ 줄 알다 is more precise when talking about a learned skill. If you just mean you're physically capable of doing it, -ㄹ 수 있다 is fine.

For example, if someone asks if you can reach a high shelf, you'd use -ㄹ 수 있다 (닿을 수 있어요), not -ㄹ 줄 알다, because reaching isn't a 'skill' in the same way playing an instrument is.

§ When to Prioritize -ㄹ 수 있다

Use -ㄹ 수 있다 when you want to express:

• General ability: "I can run fast."
• Possibility: "It might rain." or "It's possible to solve this problem."
• Circumstantial ability: "I can't go because I'm busy."

It's your go-to for a broad sense of 'can' or 'be able to'. Master this pattern, and you'll unlock a huge range of expressions in Korean!
