This document discusses how readers can use context clues to determine the meaning of unfamiliar words, just as detectives use clues to solve mysteries. It defines context clues as hints within a text that provide meaning and lists several types of context clues: definition, restatement/synonym, contrast/antonym, example, comparison, list/series, cause and effect, and description/inference. Examples are provided for each type along with practice questions to identify the context clue used. The overall objectives are to learn how to use context clues as word detectives and unlock meanings through a class app.
