Elementary - Grade 4
Lesson 4: Purpose of Movement
(-(으)러 가다 / 오다)
Why Are You Going?
You know how to say "I'm going to the library" (도서관에 가요). But *why* are you going? To study!
This grammar pattern, -(으)러 가다/오다, connects your *purpose* (the action) to your *movement* (going/coming).
It translates to "to go (in order) to..." or "to come (in order) to..."
The Two "Purpose" Rules
You attach this ending to the stem of the verb that is your *purpose* (e.g., "to study", "to eat").
Rule 1: Stem ends in a VOWEL
Add 러 가다/오다 directly to the stem.
"I am going (in order) to study."
Rule 2: Stem ends in a CONSONANT
Add 으러 가다/오다 to the stem.
"I am coming (in order) to eat."
Special Rule: Stem ends in 'ㄹ'
If the stem *already* ends in ㄹ (L) (like 놀다 - to play or 만들다 - to make), it follows Rule 1!
You just add 러 가다/오다 (no 으 needed).
"I am going (in order) to play/hang out."
Putting It All Together
Now you can explain *why* you are going somewhere.
