Just in case anyone is wondering how "zinzulation" found its way into this thread. I had a message entitled "oonomatopoieae" - which said
"Hello, jmh - zinzulation is a word I've been told about, but never found in a dictionary. Apparently, it means the plangent sound made by a metal blade such as that of a buzz saw. Have you seen it anywhere?"

I wasn't sure if it was real so I asked a few fellow a-word-a-dayers for advice. I had quite a few good responses (for which I am very grateful) and managed to formulate a reply, mainly based on a message from twusm. He managed to turn up a reference to the word - I'll let him post his answer if he wishes. I think Jeff's reply is very useful for anyone needing to check out an obscure word.
Sorry to take you off the main subject with this message.
