Ideas and words aren’t the same thing, or from the same model - words are a communication layer, with robust error correction - but ideas stem from intuition, which is more of a lossy aggregative/associative model. There’s a balance to be had in each when operating a human mind, I find - let the latter suggest ideas and potential association, let the former robustly prove or disprove them. So yes, it’s pattern matching on all levels, but pattern matching within words doesn’t produce new ideas as readily - instead the idea-space is queried directly.

IMO we really are just a bunch of models that interoperate.
