Particles: 을/를, 에, 에서
Learn object particles and location particles to build basic sentences.
This lesson introduces the three object and location particles that form the backbone of every Korean sentence: 을/를 (object marker), 에 (destination/time), and 에서 (location of action). Mastering these three is what separates 'I can say a few phrases' from 'I can build my own sentences'. The choice between 을 and 를 is purely phonological — 을 after consonants, 를 after vowels. There is no meaning difference.
에 and 에서 both relate to place, but the distinction matters: 에 marks a destination or location of static existence ('가다, 오다, 있다' style verbs), 에서 marks the place where an action happens ('하다, 먹다, 공부하다' style verbs). 'I'm going to school' is 학교에 가요. 'I'm studying at school' is 학교에서 공부해요. Native speakers feel this distinction so strongly that mixing them up is one of the few errors that can momentarily confuse them. Practice with the examples until the choice becomes automatic.
을/를 — Object Particle
을 is used after consonant-ending nouns, 를 after vowel-ending nouns. They mark the object of a verb (what you eat, drink, see, etc.).
에 vs 에서 — Location Particles
에 marks a destination or point in time ('to', 'at'). 에서 marks where an action takes place ('at', 'in'). Think: 에 = direction/existence, 에서 = action happens here.
Cultural & Language Note
을/를 corresponds to Japanese を, and 에 versus 에서 corresponds to に versus で. For a Japanese speaker this level is less about learning new concepts than about attaching known concepts to new sounds. English speakers, who mark objects by word order rather than particles, have to build the whole mechanism from nothing — which is why Level 3 is where the two audiences diverge most in difficulty.
Common Mistakes to Avoid
In casual speech Koreans drop 을/를 constantly — 밥 먹었어? rather than 밥을 먹었어? Learners who insert every particle sound like a textbook. The reverse error is dropping them in writing or formal speech, where they are expected. The 에 versus 에서 split is also not purely about location: 에 goes with existence and destination verbs, 에서 with action verbs.
