English is just one language, and while perhaps unusually expressive because of the amount of abuse it's received over the centuries, plus its ability to wholesale absorb new words on a whim, it is incapable of expressing some things with the same degree of succinctness and precision other languages have.
There are words in other languages that take a paragraph to explain in English because of all the cultural context they contain, or because they refer to things that most people who speak English have never seen, nor felt a need to describe with that degree of precision.
The problem with using English as a basis is it's very hard to explain in English what the language is incapable of expressing. This is like a fish trying to explain what they can do on land when the very concept of land is hazy at best.
We could do the same thing with languages. Say a language is "English complete" if it can express at least everything expressible in English. I suspect all commonly used modern languages are English complete. The most obvious way I can see that a language would fail to be complete would be if it lacked nonce words or any equivalent device.
