I have always wondered how denique should be stressed.
On the antepenultimate. It is not deni + que:
Yes, stress on the first syllable, but I also want to add that the finale e is short: dēnĭquĕ. Lewis & Short erroneously mark it and many other instances of final -ĕ as long: cf. https://www.jstor.org/stable/641434
Of course this wouldn’t change the pronunciation, but this is something I’ve never noticed, but I also don’t know if I’ve ever looked up denique in L&S. My Logos edition of L&S doesn’t do this, leaving the syllable unmarked:
dēnĭque…
Now I’ll have to look at some of the beginning texts I have around to see if they do it.
