The Greek alphabet has twenty-four
letters. It originated in Ionia, and was adopted at Athens in 403 B.C. The
letters from A to T are derived from Phoenician and have Semitic names. The
rest were invented by the Greeks.
From the Greek alphabet are derived the alphabets of most European countries. The
ancients used only the large letters, called majuscules (capitals as E, uncials as e); the small letters
(minuscules), which were used as a literary hand in the ninth century, are cursive forms of the uncials.
Keep in mind that our word
'alphabet' comes to us from the first two letters in the Greek,
Alpha and Beta.
The last letter in the Greek alphabet is Omega, and that's
where we get the expression "The Alpha and the Omega",
which means "The Beginning and the End", or All That Is.
