I personally think that humans easily apply structure to language that doesn’t really exist. In fact, we restructure our languages daily, as individuals, when communicating verbally and through text. We make up words and shorthands and abbreviations and portmanteaus. But I think the brain simply makes connections between words and things and the structure of speaking those words is interpreted like audio or visuals in our brains — just patterns to be placed.
Really, words, utterances by themselves, carry meaning. Language is just a structure for _us_, so to speak, that we agree on for ease of communication. I think this is why probabilistic models do so well: the ideas we all have are mostly similar, it really is about just mapping from one kind of word to another, or kind of phrase to another.
Feel free to respond, I’m most certainly out of my depth here.
