What is the part of the word added to the end of a root called?

  1. Root.

  2. Prefix.

  3. Suffix.

  4. Abbreviation.

The correct answer is: Suffix.

The term for the part of the word that is added to the end of a root is known as a suffix. A suffix is a word part that attaches to the end of a root word to modify its meaning or provide additional information about it. For instance, in the medical field, adding a suffix can change a noun into a verb or alter the function of the root word, such as in "heal" becoming "healing" when the suffix "-ing" is added. In contrast, a root is the foundational part of the word, a prefix is added to the beginning of the root, and an abbreviation represents a shortened form of a word or phrase. Understanding these components is crucial in fields like medical terminology, as they help in deciphering complex terms and their meanings.
