When you'd hear it
-잖아 is a casual spoken sentence ending, common among friends, family, and characters in dramas. In more polite conversation, speakers usually use -잖아요; it can sound insistent when used to press a point.
What learners get wrong
Unlike -지, -잖아 presents the fact as shared knowledge that supports the speaker’s point, often with a reminding or corrective tone. Use -지 when simply seeking agreement or confirming something.
