In reading history of plumbing in the "Thomas Crapper" site, I encountered the word "conduit", meaning a tube through which something flows, or through which an electric wire passes for protection.
I remember being sharply corrected for pronouncing it "cond'wit". I was told to call it "condit". Just now I looked it up, and my dictionary gives first "condoo'it" and "condit" as second.
I'd be interested to see a tabulation of how other members pronounce it.
