I probably have a bad question but would it be acceptable to speak it in a different accent. I speak Portuguese (Brazil). So can I pronounse it the same way a brazilian would?
Latin has many pronunciations nowadays (because it's mostly used in text actually), from what I understand the people who made this wonderful contribution here are using (so far) the Classical Pronunciation - like the Ancient intellectual Romans did, in Brazil when people teach Latin they either go with the Ecclesiastical Latin (id est, the pronunciation that is used by Roman Catholic church and it came from a vulgar form of pronunciation of Latin) OR they go with a "regional" vulgar Latin used historically by Portugal (and there are other "vulgar" forms, there is a Anglo form, a French and a German and probably many others)... anyway, except if you are a faithful catholic, I'd recommend you to strive to use the Classical Pronunciation by all means.
oh, I almost forgot to tell you: you can easily find on Youtube (in English), how to pronounce Latin in the Classical manner.
As you said you were dead, I wanted to write "Mortus es?" but I realized it doesn't mean "Are you dead"? A webpage told me it was an insult, is it true?
Is it rather "Es mortuus?" ?
It's the only conjugation of sum that works in this sentence. Present tense, active, 2nd person, singular.
