Synonyms are words or phrases that are similar in meaning. A synonym is one type of context clue that helps you to determine the meanings of unfamiliar words. Antonyms are words or phrases that have opposite meanings to other words or phrases. Antonym clues can help you understand new words. Sentences before or after a sentence that has a difficult word sometimes explain the meaning of the word. Sometimes we can use our own experiences, or our knowledge about a certain topic, to find out the meaning of an unfamiliar word. Word part clues.
