Although I spoke of the "root meaning" in the article, I wasn't really interested in the etymology since words usually change their meaning. Sometimes, the original meaning is instructive or sheds light on the word's present meaning, but often that's not the case. The idea of standing in the midst of something is pretty ambiguous, or it means something like knowing the subject so well that you stand under its skin, in its entrails, so you've practically become the thing at least in your mind. That kind of archaic interpretation isn't so relevant, though, to the present meanings of "under" and "stand." My analysis applies to the present-day meanings of those root words. That's what I was trying to get at. I'm talking more about those connotations than the historical meaning.
