PREFIXES AND SUFFIXES

An English word can be divided into three parts: a prefix, a stem, and a suffix. Pre- means 'before. A prefix, therefore, is what comes before the stem.

A suffix is what is attached to the end of the stem. As an example, the suffix -er (meaning 'someone who') in programmer ('a person who programmes')
