What purpose does「お願いだ」serve?


I am pretty sure I have heard people saying お願い before making a request. For
example:

お願いだ、部屋を綺麗にしてください。

The second sentence translates to " **Please** clean your room". So the
question is, what is the purpose of the お願いだ? Translating it literally would
make "Please, Please clean your room"

By the above convention, if I were to say お願いだ、部屋を綺麗にして (no ください), will the
sentence also mean "Please clean your room"?




Here お願いだ is an intensifier that stresses the meaning being conveyed. The
literal meaning is something along the lines of "This is my wish." Of course
it is often translated as "please" in accordance with English speaking
customs. Here as you have noted it presents a bit of an awkward translation
issue with ください in the same sentence.

I would understand or translate it as something like this:

> Clean your room please. I am serious.
>
> Please clean your room. For real.

Or more loosely:

> Would you mind getting your room cleaned up?

It is used in other similar situations where you can safely translate it as
"please".

> 待ってくれ、お願いだ。  
>  Wait a sec, please!
