Bennet - list of words with hidden quantity
This 37 minute long recording contains Bennett's list of words that have hidden quantity - i.e. those where the syllable is long by position, and where the vowel is simultaneously long by nature. One simply needs to memorise these quantities, and the best way to do this, is to get used to the sound of these words by ear.
The definitive list can be found on archive.org in Bennett's The Latin Language, its syntax inflections etc etc. I only record those words where there is certainty. Bennett includes a longer list of words where there is academic dispute.
