## Introduction
Until now, you have not learned how to say “I am good at something/I do something well” or “I am bad at something/I do something poorly.” In this lesson, you will learn about the words 잘하다 (to do something well) and 못하다 (to do something poorly). 못하다 is very hard to understand perfectly, so I will ease you in by introducing you to 잘하다 first.

## 잘하다: To do something well
The main meaning of 잘하다 is “to do something well.” To use 잘하다, simply place a noun in a sentence with 잘하다 as the verb.

This is easy to do with 하다 verbs (for example, 수영하다 and 공부하다) because to make a noun all you need to do is remove 하다 from those words. I discuss making non-하다 verbs into nouns in [Lesson 26](https://www.howtostudykorean.com/unit-2-lower-intermediate-korean-grammar/unit-2-lessons-26-33/lesson-26/ "Lesson 26: ~는 것 Describing Nouns with Verbs"), but the principal is the same for any noun form of a verb.

## 잘: Well
Just like 잘하다, you can use the word 잘 in sentences to indicate that one does something well. Usually, when you remove 하다 from a word, the word without 하다 becomes a noun. In this case, removing 하다 from 잘 does not make 잘 a noun. Instead, it is an adverb. The only reason this is important is so that you know that you can use 잘 in sentences just like other adverbs, in this case to mean “(to do something) well.” It is essentially the same as “잘하다,” but used slightly different.

When I first learned about 잘하다 and 잘, I was trying to understand if these two sentences were the same:
- 나는 공부를 잘해 <AudioButton src="https://www.howtostudykorean.com/wp-content/uploads/2015/04/Lesson-20-3.mp3" /> = <span class="md spoiler">I study well</span>
- 나는 잘 공부해 = I study well
- 나는 잘 공부해 = <span class="md spoiler">I study well</span>
The answer: essentially, but not entirely.
The difference is so subtle that you don’t really need to worry about it. However, when I learned this, I worried about it, so I think maybe you should worry about it too. The reason I say “don’t worry about it” is because now when I speak I can’t really distinguish the difference in meaning. The only way I could tell the difference is referring back to my old notes from 5 years ago. Nonetheless, there is a subtle difference:
나는 공부를 잘한다 = I study well, or
“나는 (noun)을 잘한다” means that, in general, your ability to do something is good. However,
- 나는 공부를 잘한다 = <span class="md spoiler">I study well</span>, or
나는 잘 공부한다 = I study well, or
“나는 잘 (verb)다” means that you can study well because of some situation (for example, maybe you have a test coming up and you are studying really hard because of that situation).

You already know the word 잘생기다 means “handsome.” That word is actually 잘 and 생기다 put together. 생기다 has a lot of meanings, but putting 잘 and 생기다 together, it sort of means “to come out well.” The opposite is true for 못생기다 (to be ugly).

Always remember to not translate directly from English to Korean, as there are so many things that are not 100% the same in both languages. For example, in English, we would never say “I don’t know well,” but in Korean, it is very common to say:
- 저는 잘 모르겠어요 <AudioButton src="https://www.howtostudykorean.com/wp-content/uploads/2015/04/Lesson-20-4.mp3" /> = <span class="md spoiler">I don’t know (well)</span>

The difference between 못하다 and 못 is the same as the difference between 잘하다 and 잘. When you say a sentence like “나는 수영을 못해” it means that in general your ability to swim is bad. Because of this, you need to be careful about the type of verb you are using in this situation. For example, you couldn’t really use the verb “to eat” in this situation, because that would mean that “in general, my ability to eat is bad.” Instead, what you would probably want to say is that “I CAN eat, but because of some situation, I can’t really eat right now.” That is when you need to use 못 instead of 못하다.

This is where it gets unnecessarily confusing. Both of those sentences could have two meanings.
The first example:

_(My translations of “… One didn’t … because something prevented him/her from …” is often simply translated to “One couldn’t” or “One can’t.” These English terms are complex, and might be related to one not doing something because something prevented them or related to one’s ability.

Confusing? Let me say this again. When you put 못 in a sentence, it can indicate that one does something poorly (or not well) OR that one does not do something because something prevented him/her from doing it. When it has the second meaning (“I didn’t do”) it is the result of some situation preventing you.
I want to take a minute to distinguish this from other negative sentences – specifically using 안 or \~지 않다 which you learned in [Lesson 8](https://www.howtostudykorean.com/unit1/unit-1-lessons-1-8/unit-1-lesson-8/). When you use 안 or \~지 않다, there is no deeper meaning that “something prevented you from doing the action.” For example, if I said:

I am just saying that I didn’t write the exam yesterday – as if yesterday specifically was _not_ the day that I was supposed to write the exam anyway (or something like that). Why would I write the exam when it is not the exam day? Of course I wouldn’t. Nothing is _preventing_ me from writing the exam. It’s just not the day to write the exam. It’s also possible that I just didn’t do the exam because I didn’t want to. Either way, nothing is preventing me from doing it, I just didn’t do it.

The word being used
Sometimes, the word being used makes it clear which meaning you are trying to express. For example, if I said:
저는 어제 학교에 못 갔어요 <AudioButton src="https://www.howtostudykorean.com/wp-content/uploads/2017/03/Lesson20-14.mp3" />, This could have two meanings:

2. I didn’t go to school well yesterday
1. <span class="md spoiler">I didn’t go to school yesterday</span> because of some situation
2. <span class="md spoiler">I didn’t go to school well yesterday</span>
Which one of those two makes sense? In situations like this, it is easy to figure out which meaning is being used. Is it possible to “go somewhere well?” I don’t think so.
A perfect real-world example of this is something that my co-worker said to me once. The school I work at was in the process of buying my plane ticket back home, and it happened to be really expensive (like, really expensive). My co-worker always wanted to go to Canada, but when she heard how much my plane ticket was, she said to herself “캐나다에 못 가겠다[.](https://www.howtostudykorean.com/wp-content/uploads/2012/07/캐나다에못가겠다.m4a)” The meaning of this sentence is not “she will go to Canada poorly” but rather “she can’t/won’t go to Canada because of some situation” (the ticket being too expensive).

Sometimes you just need to think about the context of the sentence to understand the meaning completely. For example, if you already knew for sure that a friend wrote the exam, and they later said “시험을 못 봤어요” – the sentence could only have one meaning (because you already knew that he/she wrote the exam).
Let’s look at some examples. If somebody said:
저는 밥을 못 먹어요
<TTS>저는 밥을 못 먹어요</TTS>
This could technically mean two things. It could mean:
1. That the person can’t eat (well)
2. That the person won’t eat because of some situation (most likely because he/she is full/doesn’t like that particular food, etc…)
1. <span class="md spoiler">That the person can’t eat (well)</span>
2. <span class="md spoiler">That the person won’t eat</span> because of some situation (most likely because he/she is full/doesn’t like that particular food, etc…)
In this case, the first possibility does not make sense because everybody (99.9% of the time) has the ability to eat. Therefore, this person is expressing that he/she is not going to eat because of some situation that is causing him/her to not want to eat.
