Iota
The alpha, or any other short vowel ending of a Greek prefix metamorphoses into a longer vowel, usually eta, when combining a prefix with a root word beginning with a vowel.
ETA (somethint to do with the H in greek)
Yes in the form of η,Η and it is a vowel.
The Greek name for santa is called ayos vasilis (i (long vowel) -os vas-ee-lees)
Yes. The IE has a long i sound (aye) in pie, as in die and lie. The Greek letter pi is pronounced the same way (PY).
As always with Greek language questions, it matters whether you mean Modern Greek or Classical (Ancient) Greek. In Classical Greek the English pronoun "me" can be represented by emé or me (m' before a vowel) in the accusative case, and emoí or moi in the dative. In modern Greek, it is eména or me (m') in the accusative, and mou in the dative.
Omega. *** Omega (Ωω) and Omicron (Oo). Both sound like o nowdays.
The Egyptian alphabet/language is one of the oldest known that has been recorded as of yet. The Greek alphabet is descendant of the Phoenician alphabet but the Greek alphabet is the first and oldest to record each consonant and vowel with a separate symbol.
The question doesn't make sense. A "vowel" is only one letter. So the question is asking "What one Greek letter begins with e?" I think the word you're looking for is epsilon, the fifth letter of the Greek alphabet.
The 2 letter word "uh" has the same vowel sound as "mule".
