Lexical complexity

Adding affixes to existing words (the base) to form new words is common in academic English. Prefixes are added to the front of the base (likeright arrowdislike), whereas suffixes are added to the end of the base (activeright arrowactivate). 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.
