Joseph Bottum has found a new function for this word. An extract:
"Let's coin a term for this kind of poetic, extralogical accuracy. Let's call it agenbite. That's a word Michael of Northgate cobbled up for his 1340 Remorse of Conscience — or Agenbite of Inwit, as he actually titled the book. English would later settle on the French-born word "remorse" to carry the sense of the Latin re-mordere, "to bite again." But Michael didn't know that at the time, and so he simply translated the word's parts: again-bite or (in the muddle of early English spelling) agenbite.
"Anyway, these words that sound true need some kind of name. And since they do bite back on themselves, like a snake swallowing its tail, Michael's term will do as well as any other. Ethereal is an agenbite, isn't it? All ethereal and airy. Rapier, swashbuckler, erstwhile, obfuscate, spume — agenbites, every one. Reverberation reverberates, and jingle jingles. A friend insists that machination is a word that tells you all about its Machiavellian self, and surely sporadic is a clean agenbite, with something patchy and intermittent in the taste as you say it."
