Prefixes
A prefix is an affix which is placed before the root of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix un- is added to the word happy, it creates the word unhappy.
Hello everybody! Pay close attention to the Prefixes – Suffixes list for definitions of all PREFIXES (not Suffixes) for that section in our lessons.
