What are you searching for?

In word formation exercises the learner is given the most basic form of a word, known as “the root” form. You need to change the prefix or suffix to adapt the word into the correct form and make it fit in the 8 gaps in the text so that it makes perfect sense.

The best way to do this exercise is to focus on the word class (type of word: noun, verb, adjective, adverb), grammar (singular or plural, verb tenses, +/-) and spelling. The words must be spelled correctly and if a capital letter is needed, it must be used.


You ought to think of this as a 3 step process:

What type of word do I want? Noun, verb, adjective or adverb.

What grammar is needed? Singular or plural noun, the tense of the verb

Is it affirmative or negative? Which prefix or suffix do I need?

To aid the candidate’s understanding of this part of the exam. we have included a prefix and suffix list, high frequency root words list and also example sentences with answers in the extra resource section.
