Complete the sentence. when trying to determine the meaning of an unfamiliar word, you should first replace the unfamiliar word with a synonym that you identified based on the context clues. remove the unfamiliar word from the sentence. think of an antonym for the unfamiliar word. look for context clues that indicate the word's meaning.
