The New Easy World Language

That would be great if everyone spoke the same language on our little Earth. What would it be like?:

1) VERY EASY TO LEARN, I MEAN INSANE EASY.

2) IT WOULD BE PRECISE, A WORD HAS A MEANING AND THERE IS NO 20 DIFFERENT DEFINITIONS DEPENDING ON SOME OBSCURE CONTEXT, YEAH, MAKE IT AS PRECISE AND CONCISE AS POSSIBE.

3) NO IRREGULAR SPELLINGS. NO IDIOMS.

4) NO SLANGABILITY...WHAT I MEAN HERE IS IF YOU CALL A DOG A "WOOFULEX" PEOPLE WILL SLANG IT TO "WOOF", SO WE DO NOT WANT ANY NATURAL LANGUAGE MODIFICATIONS.

5) THIS LANGUAGE WOULD STOP ALL MISTAKES THAT CAUSE ARGUMENTS BY THOSE WHO SPEAK  WHO WOULD SPEAK IT CORRECTLY.
