99. A student makes concept web flash cards to review common word parts. (return, redo, react, review, re-, rethink, again, renew, rewind). Which of the following best describes the word part shown?
Answer: D
Prefix
The word part shown in the examples provided is identified as a prefix, specifically "re-," which is used to indicate repetition or a return to a previous state.
A) Root
A root is the base part of a word that carries its primary meaning, and it cannot stand alone. In this case, "re-" does not function as a root but rather modifies the meaning of the words it precedes, thus making this option incorrect.
B) Base
A base word is the main part of a word that can have prefixes or suffixes added to it. While "re-" is involved in modifying base words, it is not a base itself; therefore, this option does not accurately describe the word part in question.
C) Suffix
A suffix is an affix that is added to the end of a word to alter its meaning or grammatical function. Since "re-" is placed at the beginning of the words listed, it cannot be classified as a suffix, making this option incorrect.
D) Prefix
The term "prefix" accurately describes "re-," as it is positioned at the beginning of the words to indicate the concept of doing something again or returning to a previous state. This aligns perfectly with the definition and function of a prefix in the English language.
Conclusion
The correct answer is "prefix" because "re-" fits the definition of a prefix by modifying the meaning of the base words it precedes. All other options are incorrect, as they either describe different types of word parts or do not apply to the function of "re-" in the given context.
