Use the prefixes pre-, re-, and mis-

Learning Objectives Define the terms 'prefix' and 'root word'. State the meaning of the prefixes pre- (before), re- (again), and mis- (wrong). Identify the prefix and root word in a given word. Combine a prefix with a root word to create a new word. Determine the meaning of a new word based on its prefix and root word. Use words with the prefixes pre-, re-, and mis- correctly in a sentence.
