Word formation is worth more exam marks than most students realize.
Cambridge Use of English Part 3 is entirely dedicated to word formation — you’re given a base word and must produce the correct form to fit the sentence. Forming abstract nouns from other word classes (adding suffixes like -tion, -ness, -ity, -ment) is one of the most tested transformations at B2 and C1.
IELTS and TOEFL writing also reward lexical variety — and the ability to shift between to inform, information, and informative in the same paragraph demonstrates the kind of range that pushes scores into Band 7+ or TOEFL 24+. This exercise trains that flexibility directly.
