Would that be li-TA-ni-ae? I've never seen it with an accent because it's always a title or heading in the liturgical books.

Accent is on the penultimate, unless short, then it is on the antepenultimate

So is the ni long or short? If long, then li-ta-NI-æ if short,li-TA-ni-æ

Note...syllables can be long even though vowel is short. It is short because followed by a vowel, to the your original inclination was right

Remember, look at the penultimate either it is to be accented, or, if short, the syllable before it

Thanks, PED! I won't be actually studying Latin until the fall, so I had no idea what the rules were for governing accents. That helps a lot. Are there a lot of rules for whether a vowel is long or short, or is that something you can explain here?

Well if we ignore poetry, which you just get a feel for (some syllables are long because ofposition in a poem, for the sake of the meter) it isn´t too hard

1. Dipthongs are always long
2. Vowels before a double consonant are generally long
3. Letters like x are considered double consonants
4. But a mute/liquid is not, so lobusta the ust is long, but in tenebræ the ne is short, because "br" is liquid

Then of course there are simply vowels you would have to memorise....as hora in the ablative the a is long, but in the nominative it is short, though spelled the same.

But long/short is not that important in ecclesiatical latin and is more for the sake of accenting. Since that is the case, you only have to look at the penultimate syllable and the rules I gave should suffice (in poetry where the rules are broken, the accents still follow what they would have been normally)

One last note enclitics attract accents, regardless of whether the pentultimate is long or short

So múlta but multáque and multǽque

Awesome, thanks!
