Prefixes and suffixes change or expand the meaning of a root word. This is evident when reviewing some of the examples above.

The prefix "pro-" is used to connote a relationship to the root word that is for, forward or before it. So the word "proactive" means to take preliminary actions before an event or situation, to act in a forward-thinking manner, in other words.
The suffix "-able" expands the meaning of a root word to suggest an ability related to or possessing a quality of it, such as in the words "comfortable" and "portable." The suffix "-less," on the other hand, creates a word that expresses a condition that is without or not affected by the root word, such as in "friendless" and "tireless."Learn more about Education
