You reach the subway gate and realize your wallet is still at the hotel. In English, you might say "I forgot my wallet." Korean usually describes what happened more precisely.
Use
깜빡했어요 when an action slipped your mind, 잊어버렸어요 when you cannot remember information, and 두고 왔어요 when you left a physical item somewhere.

깜빡했어요: an action slipped your mind

깜빡했어요 feels like "I forgot" or "It slipped my mind." It is useful for a task you meant to do.

Pronunciation
Meaning
깜빡했어요
kkam-ppak-hae-sseo-yo
I forgot / It slipped my mind
예약 확인하는 걸 깜빡했어요
ye-yak hwa-gin-ha-neun geol kkam-ppak-hae-sseo-yo

우산 가져오는 걸 깜빡했어요
u-san ga-jyeo-o-neun geol kkam-ppak-hae-sseo-yo
I forgot to bring an umbrella
답장하는 걸 깜빡했어요
dap-jang-ha-neun geol kkam-ppak-hae-sseo-yo
I forgot to reply
The reusable pattern is:
verb + 는 걸 깜빡했어요
You do not need to analyze
는 걸 during the trip. Learn the whole shape as "I forgot to do…"

잊어버렸어요: the information is gone from memory

Use 잊어버렸어요 when you cannot recall a name, word, password, or other information. The line between these expressions is not absolute, but this distinction gives a beginner a natural first choice.
