_An_ and _a_ are forms of the same word, once spelled _an_, and meaning
_one_. After losing something of this force, _an_ was still used before
vowels and consonants alike; as, _an eagle, an ball, an hair, an use_.
Still later, and for the sake of ease in speaking, the word came to have
the two forms mentioned above; and an was retained before letters having
vowel sounds, but it dropped its _n_ and became _a_ before letters having
consonant sounds. This is the present usage.
