单词 A
释义 A||
the first letter of the Roman Alphabet, and of its various subsequent modifications (as were its prototypes Alpha of the Greek, and Aleph of the Phœnician and old Hebrew); representing originally in English, as in Latin, the ‘low-back-wide’ vowel, formed with the widest opening of jaws, pharynx, and lips. The plural has been written aes, A's, As. from A to Z: see Z 3.
c1340Hampole Pr. Consc. 481 And by þat cry men knaw þan Whether it be man or weman, For when it es born it cryes swa. If it be man it says a! a! That þe first letter is of þe nam Of our forme-fader Adam.c1386Chaucer Prol. 161 On which was first i-write a crowned A, And after, Amor vincit omnia.1401Pol. Poems II. 57 I know not an a [A⃩] from the wynd-mylne, ne a b [B] from a bole-foot.1678Butler Hudib. iii. i. 1006 And loue your Loues with A's and B's.1765Tucker Light of Nat. ii. 89 Tully tells us, a hog has been known to make a perfect letter A with his snout upon the ground; but nobody ever saw, or thought it possible to see, the whole poem of Ennius scratched out in that manner: and I believe he might have added safely, that no man ever saw a single A written by a hog, without a multitude of other irregular scratches round about it.a1842Tennyson Epic 50 Mouthing out his hollow oes and aes, Deep-chested music.
The sounds now represented by A are thus symbolized in this work:—

1. ||in name|neɪm|
2. |ɛə|in bare|bɛə(r)|
3. |æ|in man|mæn|
4. |ɑː|in father|ˈfɑːðə(r)|
5. |ɔː|in water|ˈwɔːtə(r)|
6. |ɒ|in want|wɒnt|
The vowel in chant, past, varies with different speakers from 3 to 4.
1 and 2 are also commonly represented by the digraphs ai, ay, as in pain, pay, pair |peɪn, peɪ, pɛə(r)|; and 5 by au, aw, as in laud, law |lɔːd, lɔː|. Ai, ay rarely represent a diphthong ||, as in ay, Isaiah |, aɪˈzaɪə|; au is a diphthong || only in foreign words.
In unaccented syllables these vowels are modified, and obscured; thus:—

7. |ɪ|in village, marriage|ˈvɪlɪdʒ, ˈmærɪdʒ|
8. |ɪ/ə|in separate, adj.|ˈsɛpərət, -ɪt|
9. |ə|in lunar, amœba|ˈluːnə(r), əˈmiːbə|
In rapid utterance the ə may become a mere voice glide, or entirely disappear, as separate adj. |ˈsɛpərət, ˈsɛp(ə)rət, ˈsɛprət|. These phonetic variations in actual speech are reflected in variant spellings like mackarel, mackerel, mackrel; abanet, abnet; caravel, carvel; Catharine, Catherine, Cathrine; dependant, dependent; and common ‘mistakes’ in spelling, such as seperate.
II. The letters of the alphabet, or some of them, are also used to indicate serial order and distinguish things in a series, as the notes of the musical scale, the ‘quires’ or sheets of a book, classes of ships, propositions in logic, quantities in algebra, points, and hence lines and figures in geometry. As the order is in some cases fixed, A or a has some specialized uses:
1. In Music: The 6th note of the diatonic scale of C major, or the first note of the relative minor scale of C, corresponding to la in the Tonic Sol-fa notation. Also, the scale of a composition with A as its key-note; as ‘a symphony in A’.

5. In Algebra: a, b, c, and other early letters of the alphabet are used to express known quantities, as x, y, z are to express the unknown.

IV. Phrases.
1. A per se: the letter A when standing by itself, especially when making a word.
The word a was formerly spelt ‘a-per-se, a,’ that is, ‘a by itself makes the word a,’ whence also the letter itself was sometimes called A-per-se-A. So also I per se, O per se, &-per-se (and-per-se, an-per-se, ampersee).
b. Hence fig. (also formerly Apersie, Apersey, A per C) the first, chief, most excellent, most distinguished, or unique person or thing; one who is facile princeps, or in modern phrase, A 1.

2. A 1. Applied in Lloyd's Register to ships in first-class condition, as to hull and stores alike. ‘The character A denotes New ships, or Ships Renewed or Restored. The Stores of Vessels are designated by the figures 1 and 2; 1 signifying that the Vessel is well and sufficiently found.’—Key to the Register. Added to the names of ships, as ‘the fast-sailing ship ‘Sea-breeze’, A 1 at Lloyd's’, or used attributively, ‘the splendid A 1 clipper-built ship ‘Miranda’.’
Hence, fig. (familiar and savouring of commercial phraseology), A 1, or in U.S. A No. 1, is used adjectively for ‘prime, first-class’.
