~(으)ㄹ 테니까

Since it should

Detailed Explanation

  • Equivalent to "since it might..." or "since he/she might..."
  • Gives a suggestion to the listener
  • A combination of ~(으)ㄹ 터이다 (gives an intention) and ~(으)니까 (expresses a reason)
  • 1st clause: provides a reason for...
  • 2nd clause: ...the suggestion or advice


  • Can also be used at the end of a sentence (~(으)ㄹ 테니까요)
  • Only for first person subjects
  • Only verbs can precede it, but no past tense verbs
  • Difference: ~(으)ㄹ 텐데 = an actual situation for giving an assumption
  • Difference: ~(으)ㄹ 테니까 = the reason for giving an assumption (future tense, assumed)
  • Difference: 때문에 = the actual reason for something (past/present tense, actual)
  • CANNOT be used with 걱정이다, 고맙다, 미안하다

Note: Present and Future tenses are virtually identical, likely due to speaking in the Present about some near Future situation.
