"The girl drinking juice is cute."
Translation:주스를 마시는 여자아이가 귀엽습니다.
So would word order still affect this?
I believe I am likely not alone in presupposing that the expected order would have been something like
마시는 여자아이가 주스를 귀엽습니다.
여자아이가 마시는 주스를 귀엽습니다.
If I'm not alone, I would wager it's because when we hear SOV as the word order, we sort of get thrown off when something alters it, no matter how easily we can keep up with the meaning.
Both are incorrect. An adnominal adjective (an adjective which is originally an action/a descriptive verb such as 마시는 in this case) comes right before the noun, and 주스 is an object, which must come before the verb 마시-. Consequently "주스를 마시는 여자아이가 귀엽습니다." is the only correct order.
