Meaning of 'a' (Webster Dictionary)
- The first letter of the English and of many other alphabets. The
capital A of the alphabets of Middle and Western Europe, as also the
small letter (a), besides the forms in Italic, black letter, etc., are
all descended from the old Latin A, which was borrowed from the Greek
Alpha, of the same form; and this was made from the first letter (/) of
the Phoenician alphabet, the equivalent of the Hebrew Aleph, and itself
from the Egyptian origin. The Aleph was a consonant letter, with a
guttural breath sound that was not an element of Greek articulation;
and the Greeks took it to represent their vowel Alpha with the a sound,
the Phoenician alphabet having no vowel symbols.
- The name of the sixth tone in the model major scale (that in C),
or the first tone of the minor scale, which is named after it the scale

intermediate between A and B. -- A flat (A/) is the name of a tone
intermediate between A and G.
