용으로 is a grammar?
I know that 용 mean dragon but recently I stuck with 용으로 and found in google translator that 용으로 is correspond with 에 대한 and mean "for". Could you explain is it right or wrong and what this word is mean apart from "dragon"?
Example - 시간 때우기 용으로 읽었던

Question

Answer

As sww says above.  용(用) means "for", "use", etc. Here's an example when it is used in a compound word.

학생용 = for student use (e.g., not for professional use)

It can have various translations, and " 위해" does seem quite close as a synonym.

용으로 = as, for, as a way of, etc.

Answer

시간 때우기 용으로 읽었던Meaning "I can kill time for read"용 => ~위해(for(?))
