⚠️ Pitfalls to Dodge

• ❌ Treating -잖아요 as normal negative grammar → ✅ it means “you know / remember,” not “do not.”

• ❌ Using it for totally new information → ✅ use it when the listener can recognize, see, remember, or agree with the fact.

• ❌ Overusing it with strangers → ✅ it can sound too familiar or pushy if the shared-knowledge assumption is too strong.

• ❌ Using a harsh tone → ✅ 제가 말했잖아요 can sound annoyed if stressed sharply.

• ❌ Confusing -잖아요 and -죠? → ✅ -죠? asks for agreement; -잖아요 assumes shared knowledge.
