Containing multitudes

I do realise that I have a double-standard. The use of "relevancy" where "relevance" would do irritates me from Americans, but from some early modern author I doubt I would object to it. (Although in our meetings today we had "consultating group" which wouldn't do from either.) For example, I relish John Bale talking about "Antichristes noyful cattel" but if an American used "noyful" as an intense form of "annoying" I would be noyed. Maybe in future centuries people will gleefully quote George Bush-isms; they will probably seem appealingly evocative of a strange era.
