Fascinating.. Looking at the visualization of "highly connective words", my mind automatically tried to find some pattern or sense in those particular words - why are they the most connective? Does it mean that there are the most number of definitions that contain (and are related to) these words? I wonder if that signifies something about the "culture" of the English language, what people most often think/talk about when using it (edit: cats apparently! :).

As a side note, something that struck me when I first visited treegle.xyz, was that the definition of "quarrel" included the word "etc." in it:

quarrel - a small opening in window tracery, of which the cusps, etc., make the form nearly square

The use of this "etc." bugs me for some reason: it seems to assume that the reader knows how a window tracery is built, and the word adds no value to the definition - and makes me wonder what components other than "cusps" they meant.

Anyway, wonderful experiment (and project name too).
