Prefixes and Suffixes, The Basics By Joan Whetzel Words are categorized by the way they are used in grammar and as parts of speech. The word types are: verbs, nouns, pronouns, adverbs, adjectives, prepositions, interjections, and conjunctions. Words have roots, which give them their basic meaning. Yet, there are ways to tweak those words to give them new meanings - by adding prefixes and suffixs.
This unit contains 600 words in 30 lists and 30 different quizzes that are found on the standardized ACT and SAT tests. They include high frequency words that many high school students should have seen or already know. Each unit is self-sufficient and can be used throughout the year, for summer school, or homeschool ACT/SAT prep.
