The form "-다구요" and "-다고요".

[영완]

can someone tell me how to use the form -다구요 or -다고요? what are they? and what are their meanings? and what are the difference between both of them? ~감사합니다~

damnit! in that last example it should be 돈을 줬다고 instead of 돈이 줬다고 -_-

-다고 is used by itself as a quotation.

나는 끝났어요.
I finished it.

나는 끝났다고요.
I said I finished it

You can also use it to join a sentence to another verb, for example 생각하다 (to think)

대전이 재미없어. ----------------> 대전이 *재미없다고 생각해요.*
Daejeon is boring. I *think* Daejeon is boring

진수는 나에게 서울에 *간다고 알려줬어. (알려주다 to let somebody know, to inform)
Jinsoo let me know that he was on his way* to Seoul.

진수는 나에게 돈이 줬다고 말했는데, 난 못 찾아냈어. (줬다 past tense of 주다 to give)
Jinsoo said he gave the money to me, but I couldn't find it.


-다구 is actually 사투리 (dialect)- Seoul dialect, to be specific. It has the exact same meaning as -다고 but it's just the way that people from Seoul pronounce it. So if you are talking informally with somebody in email or something, they might write 다구 instead of 다고, but there's no change in meaning.
