Suffix and Prefix

What is a suffix?
A suffix is a word ending. It is a group of letters you can add to the end of a root word*
e.g. walking, helpful

*A root word stands on its own as a word, but you can make new words from it by adding beginnings (prefixes) and endings (suffixes).
For example, 'comfort' is a root word. By adding the prefix 'dis' and the suffix 'able' you can make new words such as 'discomfort' and 'comfortable'.
