The term "root" refers to the fundamental part of a word that carries its essential meaning and from which other words can be formed. In English, roots often derive from various languages, particularly Latin and Greek. For example, the root "cred" means "to believe," as seen in words like "credible," "credit," and "incredible."

In contrast, prefixes and suffixes are affixes that modify the meaning of the root but do not stand alone as complete words. A prefix is added to the beginning of a root (e.g., "un-" in "unhappy"), while a suffix is added to the end (e.g., "-ness" in "happiness").

Choosing "root" as the correct answer emphasizes its role as the core element of a word's structure, from which meanings expand through the addition of prefixes and suffixes. Understanding roots is essential for vocabulary development and comprehension, as it allows individuals to decode unfamiliar words by recognizing their foundational elements. Therefore, "C: Root" is the most accurate answer to the question about the original word in English.
