Etymology

The indefinite article is inherited from Middle English a, a reduced form of an,[2][3][4][5] inherited from Old English ān (“one”),[6][7][8][5][2] from Proto-Indo-European *oi-no- (“one”).[9] It is thus the same word as one,[10][11][12] and French un and German ein show the same identity.[10][12][13] The long vowel of ān was shortened when the word was unstressed before a noun, probably before 1150,[6] and the final -n began to be lost before consonants before 1160, perhaps as early as 1130.[2] The same split of a and an arose independently in south German dialects and in Yiddish.[2]

Earliest recorded meaning

Before a singular noun, referring to something not specifically identified: from before 1160, in the Peterborough continuation of the Anglo-Saxon Chronicle.[6] Old English got by largely without an indefinite article, saying he wæs god man for "he was a good man".[13][10]

Semantic evolution

Ayto notes that Old English used ān chiefly as a numeral, and that it emerged as an indefinite article in the middle of the 12th century.[10] The two forms separated slowly: until about 1300 an was still often used before consonants,[10] and up to 1600 and beyond it was common before every word beginning with h.[10][5] In later Middle English of the Midlands and South, the article was clearly distinguished in spelling and sound from the numeral ōn, one.[5] The older force "one, the same" lives on in phrases such as at a time.[6][7] New uses were added over time: before a person's name as a type (a Daniel come to judgment, from about 1405 in the OED), before an unknown person's name (from 1625), and before an artist's name for a work (from 1635).[6][7]

Pronunciation

Etymology

The preposition is inherited from Middle English a, also o,[8][3] inherited from Old English on, also an,[6][7][8][9][15] from Proto-Indo-European *an-.[9] It is a variant of on that lost its final -n in unstressed use before a following word, perhaps first in fixed idioms where it was felt to be almost a prefix.[6] A following consonant favoured the loss, and until the 17th century a often alternated with an before vowels.[6] The a of “twice a day” and “three dollars a kilo” is by origin this word: Merriam-Webster and Hoad keep it here,[8][3] while the OED and the Shorter Oxford now class it with the indefinite article, with which it was early identified.[6][7]

Earliest recorded meaning

Position, "in", "with", and motion, "on to": Old English, in the translation of Chrodegang of Metz and in the Anglo-Saxon Chronicle.[6]

Semantic evolution

The separate preposition went out of standard English after about 1700, replaced by the full on or in.[6] It survived in three ways: in the distributive twice a day, extended from time to space, measure, weight and number;[6][7] in set uses with a verbal noun, such as go a-begging and set a-going;[6][7][3] and as the first part of many compound adverbs, such as abed, afoot, ashore and asleep.[6][7] Shakespeare could still write “he that died a Wednesday”,[8] and the use with days of the week lives on in regional English.[6] Wright found a- before a present participle or verbal noun (I'm a-thinking) across Scotland, Ireland and many English counties.[16]

Timeline

  • Old English – in, with; on to; in expressions of time; in a state or condition.[6][7]
  • Old English – in oaths, as in a God's name (obsolete by 1679).[6][7]
  • c. 1175 – on the surface of, now only in compounds.[6]
  • before 1200 – in manner, as a purpose.[6][7]
  • before 1225 – in partition, into (obsolete by 1888).[6]
  • late Middle English – with a verbal noun taken passively, undergoing, as a preparing.[7]
  • early 16th century – with a verbal noun taken actively, as a laughing, a going.[7]

Meanings

Preposition

  1. In, to or for each; per, used before a word beginning with a consonant sound: twice a week, three dollars a kilo.[8][7][14]
  2. (dialect or archaic) On, in, at or to: We'll go a Sunday.[8][6][7]
  3. (archaic or regional) With a verbal noun, forming a verbal expression of action in progress, now usually written with a hyphen: go a-begging.[6][7][16]

Pronunciation

Etymology

The letter is inherited from Middle English a, inherited from Old English a,[1][5] from Latin A, the first letter of the Roman alphabet, which reflects Greek capital alpha Ancient Greek ἄλφα (álpha).[6][7] The Greek letter goes back to aleph of the Phoenician and ancient Semitic alphabets.[6][7] Its name in English, like that in classical Latin, is a.[6] In both Greek and Latin it stood for the vowel made with the tongue at its lowest.[6]

Earliest recorded meaning

The letter and the sound it stands for: Old English, in Ælfric's Grammar.[6] The Ormulum, about 1175, says that the first letter is called A in Latin speech.[5]

Semantic evolution

Old English distinguished a back vowel written a from a front one written æ, a contrast later lost; in modern English the letter usually stands for the vowels of man, name and father.[6] Johnson (1755) described three sounds, which he called broad, open and slender.[17] As first in the alphabet it came to label the first of a series (1340) and then the best: the highest academic mark (from 1892), and the first-class ship of Lloyd's Register, as in A1.[6][3]

Timeline

  • Old English – the letter and its sound.[6]
  • 1340 – a distinguishing letter in a series, in the Ayenbite.[6]
  • 1551 – in logic, a universal affirmative proposition.[6]
  • 1609 – in music, the sixth note of the scale of C major.[6]
  • 1612 – from A to Z, from beginning to end.[6]
  • 1816 – something shaped like the letter.[6]
  • 1892 – the highest class of academic mark.[6]
  • 1921 – chiefly in British use, a main road below a motorway.[6]
  • 1930 – a series of standard paper sizes.[6]

Meanings

Noun

  1. The first letter of the English alphabet, or any speech sound it represents.[8][14][9]
  2. The first in a series, especially the highest grade or mark.[14][9][6]
  3. (music) The sixth note of the scale of C major, or a key or scale based on it.[14][9][6]
  4. A human blood type of the ABO group.[14]
  5. Something shaped like the letter.[9][4][6]
  6. from A to Z: from start to finish, thoroughly.[14][4][6]

Usage notes

A stands before a consonant sound and an before a vowel sound, judged by the sound and not the letter: a union, a one-way street, but an MP.[4][2] A for have is a reduced form of Middle English haven from the 14th century, written coulda or mighta after an auxiliary; it was common from the 13th to the 17th century.[8][7][9] A for of, recorded from about 1275, is a weakened of, as in cuppa, kinda and lotta.[6][8][7] As a dialectal pronoun, in Shakespeare's “Now 'a is a-praying”, a is an unstressed form of the words for he, she, it or they.[7][8][6] In Scots a, also written “a'”, means all.[8] Wright lists many more dialect prefixes spelled a-.[16]
