A is the first letter of the Alphabet in most of the known languages of the earth; in the Ethiopic however it is the thirteenth, and in the Runic the tenth. It is naturally the first letter, because it represents the first vocal sound naturally formed by human organs: being the sound uttered with a mere opening of the mouth without constraint, and without any effort to alter the natural position or configuration of the lips. Hence this letter is found in many words first uttered by infants; which words are the names of the objects with which infants are first concerned, as the breast, and the parents.
