Questions & Answers about jaryoreul boksahaeseo gyosunimkke jechulhaeya haeyo.

What is the function of 를 in 자료를?

를 is the direct-object marker. It tells us that 자료 (“materials”) is what’s being acted upon by the verbs 복사하다 (“to copy”) and 제출하다 (“to submit”). After a vowel-ending noun like 자료, you use 를 (after a consonant, you’d use 을).

What does 복사해서 mean and why is -아서 used here?

복사해서 comes from 복사하다 + the connective ending -아/어서. It literally means “having copied” or “copy and then….” The -아서/어서 form links two actions in sequence (or sometimes shows reason). Here it indicates “copy (자료) and then submit.” Because 복사하다 ends in 하, -아서 becomes -해서 (so 복사하 + 아서 = 복사해서).

Can I use 복사하고 교수님께 제출해야 해요 instead of 복사해서 교수님께 제출해야 해요?

Yes. -고 also connects sequential actions (“copy and then submit”). The nuance is subtle: -아서/어서 can suggest purpose or method (“by copying…”), while -고 is a neutral sequence connector. In everyday speech, both are perfectly acceptable here.

Why is 교수님께 used rather than 교수님에게 or 교수님한테?
