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 
dislike), whereas suffixes are added to the end of the base (active 
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.

Word formation
Formal written English uses nouns more than verbs. For example, judgement rather than judge, development rather than develop, admiration rather than admire.
There appeared to be evidence of differential treatment of children.
This is reflected in our admiration for people who have made something of their lives, sometimes against great odds, and in our somewhat disappointed judgment of those who merely drift through life.
All airfields in the country would be nationalised, and the government would continue with the development of new aircraft as recommended by the Brabazon Committee.
Associated with nominalisation is the occurrence of prepositional phrases, introduced by of:
judgment of those
treatment of children
development of new aircraft
-tion is the most common suffix used in this way. For example: alteration, resignation.
However others are: -ity ability, similarity, complexity; -ness blindness, darkness, preparedness; -ment development, encouragement; -ship friendship; -age mileage; -ery robbery, bribery; -al arrival; -ance assistance, resemblance.
