PSA: Indefinite article "a" / "an"
Our last PSA was about a letter "I". Now it's time for a letter "a", and why it's sometimes "an". :lol:

—Usage noteIn both spoken and written English the choice of "a" or "an" is determined by the initial sound of the word that follows. Before a consonant sound, "a" is used; before a vowel sound, "an": a book, a rose; an apple, an opera. Problems arise occasionally when the following word begins with a vowel letter but actually starts with a consonant sound, or vice versa. Some words beginning with the vowel letter "u" and all words beginning with the vowel letters "eu" are pronounced with a beginning consonant sound, as if the first letter were "y": a union; a European. Some other spellings that begin with a vowel letter may also stand for an initial consonant sound: a ewe; a ewer. The words one and once and all compounds of which they are the first element begin with a "w" sound: a one-room apartment; a once-famous actor.
The names of the consonant letters "f", "h", "l", "m", "n", "r", "s", and "x" are pronounced with a beginning vowel sound. When these letters are used as words or to form words, they are preceded by "an": to rent an L-shaped studio; to fly an SST. The names of the vowel letter "u" and the semivowel letters "w" and "y" are pronounced with a beginning consonant sound. When used as words, they are preceded by "a": a U-turn; The plumber installed a Y in the line.
In some words beginning with the letter "h", the "h" is not pronounced; the words actually begin with a vowel sound: an hour; an honor. When the "h" is strongly pronounced, as in a stressed syllable at the beginning of a word, it is preceded by "a": a history of the Sioux; a hero sandwich. (In former times "an" was used before strongly pronounced "h" in a stressed first syllable: an hundred.) Such adjectives as historic, historical, heroic, and habitual, which begin with an unstressed syllable and often with a silent or weakly pronounced "h", are commonly preceded by "an", especially in British English. But the use of "a" rather than "an" is widespread in both speech and writing: a historical novel; a habitual criminal. Hotel and unique are occasionally preceded by "an", but this use is increasingly old-fashioned. Although in some dialects "an" has yielded to "a" in all cases, edited writing reflects usage as described above.
