Dear List, the word, Pleiades has four syllables. The three vowels should be
pronounced separately: e i a Ple i a des. The first is Pleh, and not Plee,
the next is i as in pee, next is a, as in apple, and the last is des.
Ple i a des, with the accent on the third syllable a.
Hope this helps.
Lemuel
