On a road trip a while back, RSC and I spotted a sign for this organization. I thought it was read like a nomenclatorial stutter. "Of" after "of." We set about testing manipulations and found that every other option of which we could think lent itself to misinterpretation. The National Council of English Teachers might be teachers from the UK. English Teachers Association - same problem. Society for English Education - again, not clear if it meant English the language vs. literature vs. that particular breed of education found with the Brits. This is all due, of course, to our silly decision to associate political/social grouping with language names. If the Brits spoke Flipity and we spoke Floppity, we wouldn't have this problem. Of course, we'd have the American Floppity Teachers Association, and that might just be worse.
And, in case you were wondering, yes, 'nomenclatorial' is a word.
