What is a suffix?

Prefixes and suffixes are morphemes (morphemes are the smallest grammatical units that still have meaning). In this section, we will focus on the suffix — a morpheme that we add to the end of words to change their meaning.
One root word, for example, “improve” which is a verb, can become many types of words when you add different suffixes.
That’s why it’s so vital you learn suffixes so that you can apply them to each and every single word you know to increase your vocabulary by six-fold!
