A concept map about the English articles A, AN and THE, designed for students learning English grammar. The map explains the difference between the definite article (THE) and the indefinite articles (A and AN) and shows when to use each one. A and AN are used before singular countable nouns, while the choice between A and AN depends on the initial sound of the following word. Simple examples such as a cat and an elephant help students understand and remember the main rules for using English articles.
