Spanish language Q&A Forum

Hi, I have to write an essay in Spanish about my personal life how do I say "MMA fighter" in Spanish would it "peleador de la MMA"which is what I have been taught or "luchador de la MMA" and what is the difference (I need European Spanish if that makes a difference)

"Cuánto falta?" means "how much longer".

Can't it also mean "how much do I owe you?"

For example, if you're paying for something with cash and you gave them some bills but still owe them a few coins to reach the total..?  (how many coins are still needed?)

Thank you!

Why "a"  El Cortes..." and not ..en?

Al principio, el museo iba a construirse en Madrid     is given as correct

Why is it incorrect to say

Al principio, el museo iba a ser construido en Madrid

Gracias

How would you say, "I am proud of myself" and "I will do it myself"?

The example sentence:

"En esta tienda pueden comprarse unas joyas muy bonitas."

The translation is given is 

"You can buy very nice jewels in this shop."

However could it also be translated as:

"They can buy themselves some very nice jewels in this shop." 

if we interpret the se as being an indirect object rather than passive?

Would it be more correct to change this sample sentence:
 "Puede que yo haya sido un poco brusca, pero tenía que decir la verdad."

Vs.

"Puede que yo haya ESTADO un poco brusca....."? \

Thanks for your input.
