Seeing as Latin is no longer a spoken language, there is no way to be entirely sure how the ancient Romans pronounced it. However, I have been taught to pronounce ae as a long a, i.e. puellae would be poo-ell-ay.
The Latin dipthong ae is pronounced "-ay" as in "say". Thus, Phaedo is pronounced "Fay-doh."
No 'ae' isn't a Latin word but I do not know where it comes from
ee
The latin for crown is corona -ae (fem).
'Hephaestus' can be pronounced as 'Huh-fest-us' or 'Huf-EYE-stus'. In Latin, 'ae' makes an 'EYE' sound, so I personally prefer the latter pronunciation.
singular: a, ae ae am, a with the long vowel sound plural: ae, arum, is, as, is
