That's just not how language works.
Gödel, Escher, Bach really hammered this home for me. Many ideas are easier to express in one language or another, to the point that they are practically inexpressible in another language.
This is even true in math. Based on the set of axioms you allow, you can prove certain facts. A math with different axioms may have completely different theorems, and some observable real world behavior can be better modeled under one set of axioms than another.
Language could be described as a math for personal expression and everyday life, and each language has its own axioms and theorems.
