Overlap.

I wandered down a "intellectual craftsmanship" rabbit hole found in this week's essay from Ari Weinzweig ...

Perhaps you may object that the ordinary words of common usage are often loaded with feelings and values, and that accordingly it might be well to avoid them in favour of new words or technical terms. Here is my answer: it is true that ordinary words are often so loaded. But many technical terms in common use in social science are also loaded. To write clearly is to control these loads, to say exactly what you mean in such a way that this meaning and only this will be understood by others. Assume that your intended meaning is circumscribed by a six-foot circle, in which you are standing; assume that the meaning understood by your reader is another such circle, in which he is standing. The circles, let us hope, do overlap. The extent of that overlap is the extent of your communication. In the reader’s circle the part that does not overlap - that is one area of uncontrolled meaning: he has made it up. In your circle the part that does not overlap - that is another token of your failure: you have not got it across. The skill of writing is to get the reader’s circle of meaning to coincide exactly with yours, to write in such a way that both of you stand in the same circle of controlled meaning.

Wittgenstein said, "The limits of my language mean the limits of my world."
