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

Explanation:

The word part shown is best described as a prefix.

The word part "re-" is identified as a prefix, which is a group of letters added to the beginning of a word to modify its meaning, typically indicating repetition or going back.

A) Root

A root is the fundamental part of a word that provides its core meaning. In this case, "re-" does not serve as the core meaning but rather modifies other words, which disqualifies it as a root.

B) Base

A base word is a complete word that can stand on its own and to which affixes can be added. The prefix "re-" does not function as a base since it cannot stand alone and is instead used to enhance other words.

C) Suffix

A suffix is a letter or group of letters added to the end of a word to alter its meaning. Since "re-" is placed at the start of a word and not at the end, it cannot be classified as a suffix.

D) Prefix

The option "re-" is indeed a prefix because it is added to the beginning of words to indicate repetition or returning to a previous state. This aligns perfectly with the definition of a prefix, confirming its correctness.

Conclusion

The identification of "re-" as a prefix is accurate, as it modifies the meaning of base words by suggesting repetition or a return to a previous action. Options A, B, and C fail to correctly classify "re-" due to their definitions not aligning with the characteristics of a prefix. Thus, D is the only valid choice.
