Since it is so succesful all of a sudden to discuss phonology, I should like to present to you a question:
In short: what’s up with the failing destinction between i and u in Latin?
Slightly more elaborated (I would like to present a whole line of examples, but due to the lateness of the hour, only what springs to mind is included);
in verbs: we read ‘legimus’, the i somehow being grandchild of the thematic vowel o. In the copula, however, 1. person plural is one of the thematic forms, but is read ‘sumus’. I remember having read somewhere that Octavianus is said to have pronounced sumus as simus.
nouns: the superlative of magnus is maximus - but the other day I stumbled across this form in Sallust: maxumus. And the opposite, in the same text (bel. Cat. ch. 6-7) minume instead of minime. Same chapter, legitumum for legitimum.
Today, reading Seneca (tranq. animi. ch. 9), I see him writing bybliotheca (I who thought Seneca of anyone would distinguish between iota and ypsilon) and in the samme passage monimentum instead of monumentum.
So, there you have a few examples that I can’t quite make sense of. Have they anything in common, except the obvious mixup of these two (three) vowels - what makes them similes?
