When learning Spanish, one of the most important aspects of grammar to understand is the use of articles. Articles are short words that are used to define a noun as specific or unspecific, and they come before the noun in a sentence. In Spanish, there are two types of articles: definite articles (el, la, los, las) and indefinite articles (un, una, unos, unas). They must agree in gender and number with the noun they modify. Mastering the use of articles is essential for becoming proficient in Spanish. The following exercises will help you practice using articles in different contexts.
