English Grammar Practice Test: Articles — Flashcards

Articles are adjectives that modify nouns and communicate the meaning of a sentence. They appear before nouns or a combination of an adjective or adverb and a noun. 

There are three articles in English: "a", "an", and "the". "A" and "an" are indefinite articles, while "the" is a definite article. 

Here are some rules for using articles:
Countable nouns: Use "a/an" when countable nouns are singular. For example, "There is a desk in the room".
Uncountable nouns: Do not use "a/an" when nouns are uncountable. For example, "We had fish for dinner yesterday".
Vowels and consonants: The rule for choosing "a" or "an" depends on whether the initial sound of the following word is a vowel or consonant sound. For example, "an" is used for words that begin with a vowel sound, like "an umbrella" or "an apple". "A" is used for words that begin with a consonant sound, like "a unicycle" or "a cat".
Conversations: In conversation, "the" is only used when listeners have information about the speaker's topic.
Unique and uncommon things: "The" is used before unique and uncommon things.
