Adding 가/는/도 to Grammar

~ㄹ/을 수(가/는/도) 없다 / 있다

가:

~ㄹ/을 수가 없다: Adds emphasis (can’t ➡️ can’t even / really can’t)

는:

~ㄹ/을 수는 (or 순) 없다: Comparative nuance (I cant do x, but maybe can do something else)

도:

~ㄹ/을 수도 있다: “Might” (lit: “there is also a possibility that”)

~지 못하다:

~지도 못하다 & ~지는/진 못하다: Same usage as above.

Just remember the difference in nuance:

——————————————————————————

~지(는/도) 않다

는:

지는/진 않다: Comparative emphasis nuance on not doing/being that specific thing.

‘Compared to other qualities, it’s actually not X’

‘Compared to other possibilities, X actually didn’t/won’t happen’

Stresses that the observation goes against expectations (despite what one might expect).

Ex: 술을 마신 것 같진 않았다 = She likely wasn’t drunk, but something else.

도:

지도 않다: ‘Even’ & ‘Also/Too’

‘Don’t even…; Didn’t even…’

‘Neither…; Nor was…’

‘Isn’t even…; Wasn’t even…’

먹지도 못하다 = I can’t even eat.

Korean Fractions —

When creating a fraction in Korean:

Uses Sino-Korean numbers.

The numerator (the number on the top) is said last.

Between the two, “분의” should be said.

4분의 1 = “One part of four” (lit.) = ¼

1 and 1/8 - 1과 8분의 1
