Articles. Exceptions: Choosing A or An
There are a few exceptions to the general rule of using a before words that start with consonants and an before words that begin with vowels. The first letter of the word honor, for example, is a consonant, but it’s unpronounced. In spite of its spelling, the word honor begins with a vowel sound. Therefore, we use an. Consider the example sentence below for an illustration of this concept.
Incorrect: My mother is a honest woman.
Correct: My mother is an honest woman. – Моя мать – честная женщина.
Similarly, when the first letter of a word is a vowel but is pronounced with a consonant sound, use a, as in the sample sentence below:
Incorrect: She is an United States senator.
Correct: She is a United States senator.- Она – сенатор Соединенных Штатов.
This holds true with acronyms and initialisms, too: an LCD display, a UK-based company, an HR department, a URL.
