In math, we have axioms that we assume to be true. We don't have proofs for it. Similarly english or any other natural language attempts to describe the world using words, alphabets etc. So there must be some axioms, right? Everything cannot be described / defined. But obviously, we can describe/define every word using other words. But if want to formalise it, is it possible that there would be certain words that are axioms(i.e. no definitions) and all other words would be defined using the axioms? Is such a thing possible?
