Vocative?

It's a conundrum at best, Amicus. Julius Ceasefire once said, "I speak in Latin, but I speak with forked tongue." Julius also ate at the "Y."

It's not a conundrum at all, KKKoloon, o ignorame.

"The vocative case presents little problem for English speakers. It is usually the same as the nominative, as in English, and it is used when you address someone directly. The exceptions to the rule that the vocative is the same as the nominative are summarized in the phrase, Marce mi fili, which is the vocative for Marcus meus filius, and is a convenient way to remember that all 2nd declension nouns in -us, have a vocative in -e, that the vocative of meus is mi, and that all 2nd declension nouns in -ius have a vocative in -i."
