In Classical times, no distinction was made in writing between /u/ and /w/, or between /i/ and /j/. This distinction seems to have been phonemic, because we see names like Jūlius vs Iūlus.
But are there any true minimal pairs here, where two words with different meanings are distinguished only by a vowel vs a semivowel? If not, what's the closest we can get? (Jūlius/Iūlus is pretty close for i/j, but I don't have a similarly good example for u/v.)
/kʷiː/or/kwiː/. Personally I think it makes more sense to analyze/kʷ/as a single phoneme. – Draconis Dec 04 '20 at 16:32/kʷ/choice has to do with PIE, right?Re: corpus analysis: No, I haven't. In fact it's proven less frequent than I thought. Besides plural qui and dative cui (which, I just realized don't match vowel quality either), there are just a few other occurrences of words containing cui.
Two near misses worth noting: pecuinus/equinus and qui usque/cuiusque
