An article is a word that is used before a noun to show whether the noun is referring to something specific or not.
The three articles in English grammar are “a,” “an,” and “the.” “A” and “an” are called indefinite articles because they do not refer to anything specific. “The” is called a definite article because it refers to something that is already known or specific.
The rules for using articles are as follows:
- Use “a” before a noun that starts with a consonant sound.
- Use “an” before a noun that starts with a vowel sound.
- Use “the” before a noun that is specific or already known.
- Do not use an article before a plural noun.
- Do not use an article before an uncountable noun.
