While writing my last Gent o’ Leis column, the very same one I’ve shamelessly hyperlinked here, I wanted to confirm that tobacconalian was the adjective form of tobacco. And so, I turned to your philological friend and mine, the Oxford English Dictionary, where I discovered the following citation for tobacco’s colloquial form, tobaccy:
1989 R. BARR Roseanne (1990) I. i. 6 She wore overalls and chewed tobacky, which in the early 1950’s in Salt Lake City meant that she was something of a social misfit.
And here I thought that the scholars in charge of the English language’s most comprehensive compendium were lexicographers of the Full House/Caroline in the City variety! Thank you, online OED’s quotations box, for clearing this matter up!
