Articles are words like "a", "an", and "the" that are used before nouns in English. There are two types of articles: definite articles like "the" that specify a particular noun, and indefinite articles like "a" or "an" that refer to nonspecific nouns. Articles are important in Spanish because nouns have gender, so different articles are used for masculine and feminine nouns to identify their gender.
