Affixes and roots

Adding affixes to existing words (the base or root) to form new words is common in academic English.

Prefixes are added to the front of the base (like right arrow dislike), whereas suffixes are added to the end of the base (active right arrow activate).

Prefixes usually do not change the class of the base word, but suffixes usually do change the class of the word.

The most common prefixes used to form new verbs in academic English are: re-, dis-, over-, un-, mis-, out-. The most common suffixes are: -ise, -en, -ate, -(i)fy. By far the most common affix in academic English is -ise.
