The correct answer is C. One or more syllables added to the end of a root word.
Explanation:
The word suffix refers to a morpheme or basic unit of a word composed by one or more syllables that are added to a root word (base of the word) to create a new one or to give to a word a new meaning as the form of the root word or basic word is altered. Suffixes differ from prefixes as suffixes are always added at the end of words and not at the beginning of them. For example in the word "teacher" the root or base is the verb "teach" and the "-er" is the suffix that indicates someone is performing an action this means the word "teach" has been altered and the word "teacher" means someone who teaches. Thus, it can be concluded the correct definition of the word suffix is the one or more syllables added to the end of a root word, as suffixes are morphemes that can only be added at the end of the word but never at the middle or beginning of it.
