I mean, conversationally, of course we work a little more like that (I tend to think in whole sentence blocks before I say them but I suppose they assemble themselves largely word-by-word, or word-by-word with a bit of editing).

But right now I am trying to design something -— a physical mechanism with a particular enclosure — that I cannot clearly describe (this makes it hard to research). I designed a previous version without even knowing the words that do, in fact, describe that.

I have a theory about it, animated in my mind, that I can only test by making it.

If I want you to know about it, I can either show you it or work out words to describe it, which will be inadequate to describing it.

The idea for it came from seeing things nobody has ever put into words for me.

"Next-word sayer" doesn't describe any of this process, does it?

(This is also why text-to-CAD is a bullshit idea)
