알다 vs 모르다
Practice hookContrast quizPick the right form in a mini quiz.Open →Explanation
알다 is “to know”; 모르다 is “to not know” — not 안 알다 in standard speech.
Polite: 알아요 / 몰라요. Past: 알았어요 / 몰랐어요.
알아요 can also mean “got it / understood” in conversation after an explanation.
르 irregular shows up: 모르다 → 몰라요 — drill it early.

- After reading, open Chamelingo and recycle the same pattern in a lesson or speaking practice so it enters long-term memory.
