-(으)ㄹ 테니(까)

In this lesson, we are taking a look at the structure -(으)ㄹ 테니(까). This is used often in situations where one person wants, or asks, the other person to do something. When you use it after a verb stem that ends with a consonant, you add -을 테니(까), and when the verb stem ends with a vowel, you add -ㄹ 테니(까). The original form is -을 테니까 or -ㄹ 테니까, but it is always interchangeable with -을 테니 or -ㄹ 테니, with the last letter, 까, omitted.
