기억하다 vs 기억나다: Two Ways to Remember
10-Second Answer
기억하다 (gieokhada) means to actively remember or keep something in mind — YOU do the remembering, so the thing remembered takes the object marker 을/를. 기억나다 (gieoknada) means a memory COMES BACK to you on its own — the memory is the subject, so it takes 이/가. Same root word 기억 (memory), completely different direction.
Side by Side
Quick Examples
그 사람 이름을 기억해요.
geu saram ireumeul gieokhaeyo.
I remember that person's name.
Active: you hold the name in memory — object marker 을.
그 사람 이름이 기억나요.
geu saram ireumi gieoknayo.
That person's name comes to mind.
Spontaneous: the name surfaces on its own — subject marker 이.
갑자기 기억났어요!
gapjagi gieoknasseoyo!
It suddenly came back to me!
The "aha!" moment is almost always 기억나다, not 기억하다.
The Feeling Difference
기억하다 is deliberate: memorizing a password, keeping a promise in mind ("이거 꼭 기억해" — remember this!). 기억나다 is involuntary: a song triggers a memory, a face suddenly clicks. English "remember" covers both, which is exactly why this pair trips up English speakers — Korean splits the experience into who's doing the work.
The negative follows the same split: 기억이 안 나요 ("it's not coming to me") is what you say when you've forgotten something in the moment — much more common than 기억 안 해요, which sounds like you're refusing to remember.
Common Mistakes
Mistake #1 — Using 을/를 with 기억나다
기억나다's memory is the SUBJECT: 이름이 기억나요, never 이름을 기억나요.
Mistake #2 — Saying 기억 안 해요 for "I can't remember"
That sounds like willful refusal. "It's not coming to me" is 기억이 안 나요.
