This document provides an introduction to articles in English grammar. It defines articles as words that identify or modify nouns. There are two main types of articles: indefinite articles (a, an) and definite articles (the). Indefinite articles are used with non-specific or unknown nouns, while definite articles are used with specific or known nouns. The document goes on to explain rules for using indefinite and definite articles, including exceptions when articles are omitted. Examples are provided throughout to illustrate the rules and proper usage of articles.
