答案
A root word is the basic word without any prefix or suffix added. A prefix is added to the beginning of a root word, and a suffix is added to the end of a root word. For example, in the word "unlocked":
"un-" is the prefix,
"lock" is the root word,
"-ed" is the suffix.
"un-" is the prefix,
"lock" is the root word,
"-ed" is the suffix.
