(으)니까

Description

Adjective/Verb + (으)니까  : This pattern is equivalent to the phrase because of sth. The clause that it is added onto is the cause, and the clause that follows it is the result. This phrase is especially used when the result is an imperative or a proposative (let's ...).

Notes

• In the other main usage of this ending, it serves as a temporal marker which also carries a sense of discovery of affirmation of what follows in the next clause.
