Cambridge English word formation online training tool
This little free tool can help you train your English word formation skills. A part of the Cambridge certificate exam is about forming
the right word form when given the stem of a word. This tool can help you improve on that part of the test.
The tool can be used for First Cambridge English (FCE), Cambridge Advanced English (CAE), and Cambridge Proficiency English (CPE) - just select your difficulty level below, though the presented words are not explicitly related to the different exams.
Enter each word on separate lines. Multiple words often exist.
