Resentment of jargon comes from several sources, as we have already seen: resistance to being left out of an in-group conversation; fear (often transmuted, as a defense mechanism, into dislike or even hatred) of what is not understood or recognized; suspicion that something subversive may be going on, enabled by a code or cipher; and, on the other hand -- if it is indeed another hand -- aesthetic recoil at language that is perceived as ugly, pretentious, or anomalous. Nonetheless, I want to insist here that jargon is language in action, or rather, that jargon is a sign that something is happening in language.
