A

A or a is the first letter of the English alphabet. The small letter, a or α, is used as a lower case vowel.^[1]

When it is spoken, ā is said as a long a, a diphthong of ĕ and y. A is similar to Alpha of the Greek alphabet. That is not surprising, because it means the same sound.

"Alpha and Omega" (the last letter of the Greek alphabet) means from beginning to the end. In musical notation, the letter A is the symbol of a note in the scale, below B and above G.

A is the letter that was used to represent a team in an old TV show, The A-Team. A capital a is written "A". Use a capital A at the start of a sentence if writing.

A is also a musical note, sometimes referred to as "La".
