Word formation - word families
More than 350 useful words seek their family members. In the first 11 exercises the words appear in alphabetical order, and the last two (No 12 and 13) were made to serve as diagnostic tests. You can do No 12 first and when you have practised quite a lot, you finish off with No 13. If you are the superstitious type and think that 13 is an unlucky number, do it the other way around.
