The document provides an introduction to using articles (el, la, los, las) with nouns in Spanish. It explains that Spanish has four words for "the" while English only has one. It then discusses how nouns in Spanish are either masculine or feminine, and how the articles el and la are used depending on the gender of the noun. Some common rules for determining gender based on endings such as -o or -a are presented. Examples are provided to illustrate using articles with singular and plural nouns.
