I only really know Japanese but I was just recently looking at pitch accent stuff. Aside from a few dialects that have word level pitch accent, most dialects have specific rules about how pitch is treated based on the pitch accent certain sets of words had at an earlier stage of the language. But to simplify a lot and not bring in recent borrowings or anything like that...LinguoFranco wrote: ↑11 Jun 2018 18:34I'm trying to understand how morae work. If I'm understanding it correctly, then a basic syllable such as V or CV are 1 mora, or a light syllable, while something like VV or CVV or even CVC in some languages are 2 morae, or a heavy syllable. I'm guessing this is the basis for stress in a word? What if a word had, say, a total of 4 morae (like CVV.CVV) or something, would they both be stressed?
Also, why do something languages treat a CVC syllable with a coda sonorant as heavy, while those with an obstruent coda are light?
The second part of a 2 mora syllable is considered unable to accept the tone drop - whether it is a second vowel, the syllabic nasal, or the doubling of the consonant of the next mora. So, if for other reasons the tone drop would normally be on that "defective" mora, it moves back to the main mora in the same syllable. For your example of two heavy syllables in a row, it's a little harder because it's likely it would be a compound word, which have their own rules, but tend to leave the accent to the second part of the compound. The most likely pitch accent would be either unaccented or CVV.CV'V with the apostrophe marking where the downstep is.
