On one hand language controls the "knowing" of the other ways of knowing, yet on the other hand without the other ways of knowing there wouldn 't be any language to communicate with, since no one would have the knowledge to use language.
If we talk about knowing something then knowing means to have (acquire) knowledge either through observations, learning or information. Knowledge is the awareness and understanding of facts, truths or information gained in the form of experience or learning. In Maths for example, you learn the basic rules of geometry, algebra and calculus. With the knowledge of those basic rules you can deduct more specific and complex rules and formulas to suit the given problem. This is only possible if you "know" the basic rules and the "language" of math. Therefore the main statement above could be proven as correct.
"Language is a process of free creation; its laws and principles are fixed, but the manner in which the principles of generation are used is free and infinitely varied. Even the interpretation and use of words involves a process of free creation." - Noam Chomsky
This quote means that any language has a basic structure (grammar) on which the entire act of communication is based upon. But the content of a language (vocabulary) has an infinite variety. Therefore you can inform the doctor about your sickness / symptoms in a thousand different ways but you would still
