Definition: Expressing Inability and Prohibition
The concept of “can’t” in Korean encompasses both inability and prohibition. Inability refers to the lack of skill, capacity, or opportunity to perform an action. Prohibition, on the other hand, indicates that an action is not allowed or permitted. Korean offers several grammatical structures to express these nuances, each with its specific context and usage. Understanding these structures is essential for clear and accurate communication.
Specifically, Korean uses different particles, auxiliary verbs, and sentence endings to convey the meaning of “can’t.” These elements work together to specify whether something is impossible due to a lack of ability, external constraints, or because it is forbidden. Mastering these intricacies is key to achieving fluency and avoiding misunderstandings.
Structural Breakdown: Key Grammatical Patterns
The primary ways to express “can’t” in Korean involve using the adverb 못 (mot), the grammatical structure ~지 못하다 (~ji mot hada), the prohibition marker ~(으)면 안 되다 (~(eu)myeon an doeda), and the expression ~(을) 수 없다 (~(eul) su eopda). Each of these structures has its own specific grammatical rules and usage contexts.
Let’s break down the basic structure of each of these forms. The adverb 못 typically precedes the verb, indicating an inability to perform the action. The structure ~지 못하다 attaches to the verb stem and also expresses inability. The pattern ~(으)면 안 되다 is used to express prohibition, meaning something “should not” or “must not” be done. Lastly, ~(을) 수 없다 expresses impossibility, often due to external circumstances or a lack of capacity.
Types and Categories of “Can’t” in Korean
못: Expressing Inability Due to Lack of Skill or Circumstance
The adverb 못 (mot) is one of the most common ways to express “can’t” in Korean. It indicates an inability to perform an action, often due to a lack of skill or unfavorable circumstances. 못 is placed directly before the verb it modifies.
For instance, if you want to say “I can’t swim,” you would say “수영 못 해요” (suyeong mot haeyo). Here, 못 is placed before the verb 하다 (hada), which is used with the noun 수영 (suyeong) to mean “to swim.” This construction is simple and widely used in everyday conversation.
~지 못 해(요): Another Way to Express Inability
The structure ~지 못하다 (~ji mot hada) is another common way to express inability. It’s slightly more formal than using 못 alone, but it conveys the same basic meaning. The verb stem is followed by ~지 못하다.
For example, “I can’t eat spicy food” can be expressed as “매운 음식을 먹지 못해요” (maeun eumsigeul meokji mot haeyo). Here, 먹다 (meokda, “to eat”) becomes 먹지 못하다 (meokji mot hada), indicating the inability to eat spicy food.
~(으)면 안 돼(요): Expressing Prohibition
To express prohibition, Korean uses the structure ~(으)면 안 되다 (~(eu)myeon an doeda). This pattern means “must not” or “should not” and is used to indicate that an action is not allowed. The choice between ~으면 and ~면 depends on whether the verb stem ends in a consonant or a vowel, respectively.
For example, “You can’t smoke here” is expressed as “여기서 담배를 피우면 안 돼요” (yeogiseo dambaereul piuumyeon an dwaeyo). Since the verb 피우다 (piuda, “to smoke”) ends in a vowel, the form ~면 is used.
~(을) 수 없어(요): Expressing Impossibility
The structure ~(을) 수 없다 (~(eul) su eopda) is used to express impossibility, often due to external circumstances or limitations. It translates to “it is impossible to” or “I cannot” in a more absolute sense. The choice between ~을 and ~ㄹ depends on whether the verb stem ends in a consonant or a vowel, respectively.
For instance, “I can’t go because I’m busy” can be expressed as “바빠서 갈 수 없어요” (bappaseo gal su eopseoyo). Here, 가다 (gada, “to go”) becomes 갈 수 없다 (gal su eopda), indicating the impossibility of going due to being busy.

Usage Rules: Ensuring Grammatical Accuracy
When using these expressions, it’s vital to follow specific grammatical rules to ensure accuracy. For 못, always place it directly before the verb. For ~지 못하다, ensure the verb stem is correctly conjugated with the ~지 ending. With ~(으)면 안 되다, remember to choose between ~으면 and ~면 based on the verb stem’s ending. Lastly, for ~(을) 수 없다, select ~을 or ~ㄹ depending on the verb stem’s final consonant or vowel.
It’s also important to consider the context. 못 and ~지 못하다 are generally used for inability, while ~(으)면 안 되다 is exclusively for prohibition. ~(을) 수 없다 expresses a stronger sense of impossibility, often related to external factors.
Common Mistakes: Avoiding Typical Errors
One common mistake is misplacing 못 after the verb instead of before it. For example, saying “운전 해요 못” (unjeon haeyo mot) instead of “운전 못 해요” (unjeon mot haeyo). Another error is incorrectly conjugating the verb stem with ~지 못하다, such as using “먹 못해요” (meok mot haeyo) instead of “먹지 못해요” (meokji mot haeyo).
With ~(으)면 안 되다, forgetting to choose the correct ending (~으면 or ~면) is a frequent mistake. For instance, saying “피우으면 안 돼요” (piuueumyeon an dwaeyo) instead of “피우면 안 돼요” (piumyeon an dwaeyo). Similarly, with ~(을) 수 없다, learners often struggle with the correct particle, saying “갈 수 없다” (gal su eopda) when the stem ends in a vowel and “먹을 수 없다” (meogeul su eopda) when it ends in a consonant.
Finally, using the wrong expression in the wrong context is a common error. For example, using 못 to express prohibition instead of using ~(으)면 안 되다. For instance, saying “여기서 담배 못 해요” (yeogiseo dambae mot haeyo) instead of “여기서 담배를 피우면 안 돼요” (yeogiseo dambaereul piumyeon an dwaeyo).
