A A ( named ā in the English, and most commonly ä in other languages ). 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 Phœnician 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 ä sound, the Phœnician alphabet having no vowel symbols. This letter, in English, is used for several different vowel sounds. See Guide to pronunciation , §§ 43-74. The regular long a , as in fate , etc., is a comparatively modern sound, and has taken the place of what, till about the early part of the 17th century, was a sound of the quality of ä (as in far ). 2. (Mus.) 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 in A minor. The second string of the violin is tuned to the A in the treble staff. -- A sharp (A♯) is the name of a musical tone intermediate between A and B. -- A flat (A♭) is the name of a tone intermediate between A and G. A per se (L. per se by itself), one preëminent; a nonesuch. [ Obsolete]

Of Troy and Greece.

A A (ȧ emph. ā). 1. [ Shortened form of an . Anglo-Saxon ān one. See One .] An adjective, commonly called the indefinite article, and signifying one or any , but less emphatically. "At a birth"; "In a word"; "At a blow". Shak. It is placed before nouns of the singular number denoting an individual object, or a quality individualized, before collective nouns, and also before plural nouns when the adjective few or the phrase great many or good many is interposed; as, a dog, a house, a man; a color; a sweetness; a hundred, a fleet, a regiment; a few persons, a great many days. It is used for an , for the sake of euphony, before words beginning with a consonant sound [ for exception of certain words beginning with h , see An ]; as, a table, a woman , a year, a unit, a eulogy, a ewe, a oneness, such a one, etc. Formally an was used both before vowels and consonants. 2.

" It was a doing." Shak. "He burst out a laughing." Macaulay. The hyphen may be used to connect a with the verbal substantive (as, a -hunting, a -building) or the words may be written separately. This form of expression is now for the most part obsolete, the a being omitted and the verbal substantive treated as a participle.

4. (Mar. Law) To relinquish all claim to; -- used when an insured person gives up to underwriters all claim to the property covered by a policy, which may remain after loss or damage by a peril insured against. Syn. -- To give up; yield; forego; cede; surrender; resign; abdicate; quit; relinquish; renounce; desert; forsake; leave; retire; withdraw from. -- To Abandon , Desert , Forsake . These words agree in representing a person as giving up or leaving some object, but differ as to the mode of doing it. The distinctive sense of abandon is that of giving up a thing absolutely and finally; as, to abandon one's friends, places, opinions, good or evil habits, a hopeless enterprise, a shipwrecked vessel. Abandon is more widely applicable than forsake or desert . The Latin original of desert appears to have been originally applied to the case of deserters from military service. Hence, the verb, when used of persons in the active voice, has usually or always a bad sense, implying some breach of fidelity, honor, etc., the leaving of something which the person should rightfully stand by and support; as, to desert one's colors, to desert one's post, to desert one's principles or duty. When used in the passive, the sense is not necessarily bad; as, the fields were deserted , a deserted village, deserted halls. Forsake implies the breaking off of previous habit, association, personal connection, or that the thing left had been familiar or frequented; as, to forsake old friends, to forsake the paths of rectitude, the blood forsook his cheeks. It may be used either in a good or in a bad sense.
