*See Also : an

In modern written English, the form a is used before a word beginning with a consonant sound, however it may be spelled ( a frog, a university, a euphemism). The form an is used before a word beginning with a vowel sound ( an orange, an hour). At one time, an was an acceptable alternative before words beginning with a consonant sound but spelled with a vowel ( an one, an united appeal), but this usage is now entirely obsolete. · An was also once a common variant before words beginning with h in which the first syllable was unstressed; thus 18th-century authors wrote either a historical or an historical but a history, not an history. This usage had a phonetic justification inasmuch as the initial h in words such as historical and heroic was often dropped, a practice that was largely abandoned by the late 19th century in educated speech. By 1926 H.W. Fowler could regard the continued use of an before such words as pedantic. Nowadays it survives primarily before the word historical; one rarely encounters a reference to an hysterectomy or an hereditary trait. The use of a phrase like an historic opportunity is a harmless adornment in formal writing.
在现代书面英语中 a的形式用于以辅音开头的单词前，但这个词可能被拼成（ a frog，a university，a euphemism）。 an的形式用于以元音开头的词前（ an orange，an hour）。有一度 an用于以辅音开头但拼写形式为元音的单词前的形式也被认可（ an one，an united appeal），但这种用法现在已被废弃了。 An曾是用于第一个音节不重读，且以 h为开头的单词前的一种常见变体形式；所以18世纪的作家既可用 a historical也可用 an historical，但不可用 a history也不可用 an history。当 h在这样一些单词，如 historical和 heroic中作为起首字母而又不发音时，这种用法在语音学上是合理的。这种用法在19世纪末的高雅用语中已基本废弃了。1926年时H·W·福勒还认为 an继续在这些单词前使用太具学究气了。现在这种用法主要在 historical前时还保存使用；在 an hysterectomy或 an hereditary trait之前则极为少见。在正式的书面语中，象 an historic opportunity这种用法也不失为一种装饰
