Level 5 Lesson 27 / -잖아(요) / You know, Isn't it, You see..., Come on...In this lesson, we are looking at a very popular verb ending in Korean, -잖아(요) [-ja-na(-yo)]. -잖아(요) is used in various contexts and therefore has various meanings, but you can use -잖아요 most commonly when you want to ask the other person to agree with you or when you are correcting the other person's remark.Meaning of -잖아(요)- 잖아(요) originally comes from the structure -지 않아(요) (Go to Level 1 Lesson 21 to review on this grammar point.), which means "to not + Verb", but now has an indepenent meaning is that quite different from the original form.When you attach -잖아(요) at the end of a verb stem, the sentence takes the meaning of "You see?" "No, that's not true. In fact, ..." "Come on, ..." etc. So you can use this structure when you are correcting what someone else said or insisting that what you are saying or have said is correct. You can also sometimes use -잖아(요) when you are providing an excuse or a reason for something.ConstructionVerb stem + -잖아 (Casual form)Verb stem + -잖아요 (Formal form)Verb stem + -잖습니까 (Most formal form)Past TenseVerb stem + -았/었/였 + -잖아(요)Future TenseVerb stem + -(으)ㄹ 거 + -잖아(요)Examples and comparisons with -지 않아(요)1. 춥다 [chup-da] = to be coldPlain present tense: 추워요.
