B2 First: use of English part 3 (word formation with irregular nouns and verbs)

There are lots of standard verb suffixes (see my verb word formation pages) or noun suffixes (e.g -ment, -ion). But many nouns and verbs have irregular suffixes which you'll need to know for the B2 First (FCE) exam.

Look at the information in the table for a few minutes and try to remember the words. Then click below to hide the information and try to answer the questions at the bottom.

Note: there may be other forms of these words (for example, marriageable), but I have tried to give the most common/useful examples above ("a woman of marriageable age" sounds very old-fashioned nowadays).
