Question Author
I am not reluctant to accept TART as the answer, it's obviously the correct one. It's just that I have never heard of the word Tom used with this meaning. The Shorter Oxford Dictionary is also blissfully unaware of this meaning as are several on-line dictionaries. Tom has got such masculine connoctations that it seems to me surprising that it has been used for a prostitute. Of course, in these liberated and enlightened times the word prostitute may not only apply to the female sex. Still, I do believe it to be an unusual adaptation. Does anyone know of the derivation of the word TOM in this particular use? Stew.
