⚠️ Pitfalls to Dodge

• ❌ -았던/었던 = any past tense → ✅ It modifies a noun and often carries a completed/disconnected memory feeling.

• ❌ Treating -던 and -았던/었던 as always identical → ✅ -았던/었던 tends to sound more finished or cut off from now.

• ❌ 먹던 케이크 when you mean “the cake I tried before” → ✅ 먹어 봤던 케이크 or 먹었던 케이크, depending on the intended nuance.

• ❌ 학생였던 사람 → ✅ 학생이었던 사람. A consonant-ending noun uses 이었던.

• ❌ Overusing it for current habits → ✅ If the habit is still current, use a present modifier like 자주 가는 카페 (the café I often go to).
