Don’t mix up
-(으)ㄹ진대vs-(으)니까-(으)니까 is the neutral everyday reason marker; -(으)ㄹ진대 is bookish and leads to a principled conclusion: 비가 오니까 우산을 가져가세요 (not 비가 올진대).How to build it
알다 → 알진대, 평등하다 → 평등할진대, 주인이다 → 주인일진대, 애쓰다 → 애썼을진대
- It belongs to formal writing, speeches, editorials and sayings; in everyday conversation it sounds archaic or comic, so use -(으)니까 there.
- The second clause is usually a rhetorical question (-겠는가, -(으)랴), an obligation (마땅히 -아/어야 한다) or a strong judgement; it often pairs with 하물며.
- The first clause should be a premise the listener is expected to accept (a truth, principle or known fact), not a new or uncertain piece of information.
- It is a connective ending and cannot close a sentence; past premises take -았/었을진대.
