   • 1929, Martin Armstrong, The Sleeping Fury, book 1 Charlotte At Fifty, chapter 1:

     “Halnaker is the family name?”
     “Yes. Spelt H-a-l-n-a-k-e-r and pronounced Hannaker, with the accent on the Hann—the pro-penultimate, as we were taught to call it at school. The propenultimate, if you please. What unmitigated nonsense! Why not the last-but-two?”

   • 1997, Georg Capellanus and Rod McLeod, Latin Can be Fun (Facetiae Latinae): A Modern Conversational Guide (Sermo Hodiernus Antique Redditus):
