The first letter of the English and most other alphabets, is frequently used as an abbreviation, (q. v.) and also in the marks of schedules or papers, as schedule A, B, C, &c. Among the Romans this letter was used in criminal trials. The judges were furnished with small tables covered with wax, and each one inscribed on it the initial letter of his vote; A, when he voted to absolve the party on trial; C, when he was for condemnation; and N L, (non liquet) when the matter did not appear clearly, and be desired a new argument.

the first letter in our alphabet, its corresponding symbol standing first also in many other alphabets derived from the Phoenician. It originated in the hieroglyphic picture of an eagle (Old Egyptian ahom), the cursive hieratic form of which was the original of the Phoenician aleph, an ox, from a fancied resemblance to its head and horns.--A, as a note in music, is the major sixth of the scale of C; A1, the symbol by which first-class vessels are classed in Lloyd's Register of British and Foreign Shipping, hence first-rate.
the indefinite article, a broken-down form of An, and used before words beginning with the sound of a consonant. [An was a new development, after the Conquest, of the A.S. numeral Ã¡n, one.]
Ã¤ or [=a], a prep., derived from the old prep. on, and still used, as a prefix, in afoot, afield, apart, asleep, nowadays, twice-a-day; also with verbal nouns, as a-building, to be a-doing, to set a-going. It is now admitted only colloquially. [Short for A.S. an, a dialectic form of on, on, in, at. See PREFIXES.]
Ã¤, a dialectic corruption of he or she, as in quotha, (Shak.) 'A babbled of green fields.'--A, usually written a', Scotch for all; A, a form of the L. prep. ab, from, of, used before consonants, as in Thomas Ã Kempis, Thomas Ã Becket, &c.
