This document discusses dictionaries and how they can be used. It begins by asking why we use dictionaries and how they are useful. Dictionaries are used to find definitions of unknown words, check spellings, and determine word classes. They can also provide extra vocabulary knowledge. The document then explains how to use dictionaries by finding words alphabetically and defining what a definition is. It concludes by listing different types of dictionaries that can be used, such as online, books, and foreign language dictionaries, and provides an example activity to look up word definitions.
