(Dee - A tra ah) Three syllables. The First a stands alone. In Early Modern English, a double a indicates a long sound - which Dee indicates for the second syllable in his phonetic note.
(Dee - atraâh) See the 48 Claves. Here Dee placed a circumflex over the third a. Dee seems to have used âh to indicate a vowel sound similar to what we hear in the English words father and fall.
