Verbs to nouns

A lot of verbs can be changed to nouns by the addition of a suffix (e.g., perform -
performance, arrange - arrangement, fail - failure, etc), or by changing other features of the
word (e.g., prove - proof, be born - birth, etc).
In many cases, these nouns are abstract. This means that we cannot usually touch, see, feel,
hear or smell them.
Look at these sentences, and complete the crossword puzzle with a noun form of the verb at
the end of each sentence. Make sure that you use the correct suffix or make other necessary
changes.
