The indefinite article takes two forms. It’s the word a when it precedes a word that begins with a consonant. It’s the word an when it precedes a word that begins with a vowel. The indefinite article indicates that a noun refers to a general idea rather than a particular thing. For example, you might ask your friend, “Should I bring a gift to the party?” Your friend will understand that you are not asking about a specific type of gift or a specific item. “I am going to bring an apple pie,” your friend tells you. Again, the indefinite article indicates that she is not talking about a specific apple pie. Your friend probably doesn’t even have any pie yet. The indefinite article only appears with singular nouns. Consider the following examples of indefinite articles used in context:
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.
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:
This holds true with acronyms and initialisms, too: an LCD display, a UK-based company, an HR department, a URL.
Sometimes an article modifies a noun that is also modified by an adjective. The usual word order is article + adjective + noun. If the article is indefinite, choose a or an based on the word that immediately follows it. Consider the following examples for reference:
Uncountable nouns are nouns that are either difficult or impossible to count. Uncountable nouns include intangible things (e.g., information, air), liquids (e.g., milk, wine), and things that are too large or numerous to count (e.g., equipment, sand, wood). Because these things can’t be counted, you should never use a or an with them—remember, the indefinite article is only for singular nouns. Uncountable nouns can be modified by words like some, however. Consider the examples below for reference:
