To reply to wow's question. "Why the but?".....

Because.

Further Comment on the original post...

Adding the "but" to the end is simple mangulation of the language through an unnecessary rearranging of the sentence structure. (Maybe that's what an anastrophe is - haven't looked that one up yet.)

Finally, to knock the issue of whether there's a rising or falling inflection on the head - THERE'S NONE!! As a proud user of the word (well, I know it's bad - but hey, this discussion has proven that it's unique!!!), I can say with with authority that it's delivered in a deadpan/laconic manner.

I'm still gonna use it but.
