LEARN KOREAN (한국어) [GRAMMAR] #1

잘 AND 못 WITH COMPARATIVES AND SUPERLATIVES

One final thing. You learned about using ~보다 and 가장/제일 to make comparative and superlative sentences. The concepts you learned are very commonly used alongside ~보다 or 가장/제일 in sentences to say that somebody can do something better/worse, or do something the best/worst. Some examples:

Comparative Sentences:
우리 아들은 친구들보다 축구를 더 잘해요 - Our (my) son is better than (his) friends at soccer
그 교수는 다른 교수들보다 수업을 더 잘해요 - That professor teaches classes better than other professors
저는 수영을 작년보다 더 잘해요 - I am better at swimming than last year

Superlative Sentences:
우리 아들은 축구를 가장 잘해요 - Our (my) son is the best at soccer
그 교수는 수업을 제일 잘해요 - That professor teaches classes the best (is the best at teaching classes)

저는 축구를 제일 못해요 - I play soccer the worst
저는 수영을 제일 못해요 - I swim the worst

Again, in most situations, these sentences would sound more natural with the use of other grammatical principles. For example, to say "I am the one who plays soccer the worst" or "Of all people, I play soccer the worst." To be able to wrap your head around those sentences, you'll need to read/understand the grammar in later lessons.
