The difference between 못 and 안-

I wish someone had explained this to me at the beginning. Normally my teacher would just correct me every time without explanation when I used either 못mot / not or 안-an- / not. Someone had half explained that 못mot / not means something more like "can't/couldn't" but it didn't seem to fit. After all, you don't normally answer the question "did you see Phil" with "no, I couldn't see him." The answer would be "no, I didn't see him"

In Korean, however, you answer this question with 못mot / not, not 안-an- / not. The difference, in theory is pretty simple. In practice, for English speakers it's a little more difficult. We don't think about this circumstances of why something "isn't" nearly as much as Koreans. For us, something simply "is" or "isn't". But basically put:

• 못mot / not is used for when something didn't happen because of external factors
• 안-an- / not is used for something which didn't happen because of you, you didn't want to, or you didn't choose to

Imagine your teacher asked you: "Have you done your homework?" If you hadn't done it how would you answer? In English you just say "I didn't do it because...", but in Korean if you say: "숙제 안했어요sukje an-haesseoyo / I didn't do my homework" it means you didn't want to, and there is no real excuse. If you say "숙제 못 했어요sukje mot haesseoyo / I didn't do my homework" it means there is a reason that you didn't do it. So which one would you answer with?

Here are some other phrases where 못mot / not is more common than 안-an- / not:

• 비터 만났어요? / 아니요, 못 만났어요peter mannass-eo-yo? / aniyo, mot mannass-eo-yo / Did you meet Peter? No I didn't. - you couldn't meet him because you were sick
• 김치 많이 먹어요? / 아니요, 못 먹어요kim-chi mani mog-eo-yo? / aniyo, mot mog-eo-yo / do you eat a lot of kimchi? No I don't - you don't eat it because it's spicy
• 장학금 받았어요? / 아니요, 못 받았어요jang-hak-geum padass-eo-yo? / aniyo mot padass-eo-yo / did you get a scholarship? No I didn't. - you didn't get it because you grades weren't good enough

Two of those sentences would be strange if you used 안-an- / not. And one would be ok. Which ones?
That's right! If someone asks you: 김치 많이 먹어요?kim-chi mani mog-eo-yo? Do you eat a lot fo kimchi, you can answer 아니요, 안먹어요aniyo, am-mog-eo-yo / do you eat a lot of kimchi? No I don't. But that would mean that you don't eat it because it's spicy, you don't eat it because you choose not or don't want to.

So for the other two sentences, especially with number three, you can't really use 안-an- / not at all. Who doesn't want to get a scholarship? And why did you choose not to meet Peter? You don't like him?

I hope that's clear! Easy to understand, but a little complicated to put into practice. Now every time I hear 못mot / not or 안-an- / not Im going to be thinking about this, and then try to use it myself.
