I keep thinking there's a word I know of that ends in -most but which  
doesn't actually come from compounding with the word most, but I  
can't seem to think what it is. (As I recall, it originally ended in - 
mest, which consisted of the final -m of the root and the superlative  
morpheme -est, but was later remodeled by analogy to <most>.)

I've always heard <provost> with a long O. The AHD, at least, shows  
that as the majority pronunciation, followed by one with /@/, but  
none with a "short O". But YMMV.
