Note:
• The prefixes un- and in- are used before adjectives and adverbs to give them the opposite
meaning (usual – unusual, correct – incorrect).

• Instead of in- we use the prefixes im- (when the word starts with m or p), il- (when the word starts
with l) and ir- (when the word starts with r).

• The suffix -ful is used after a noun to form an adjective which means ‘having enough of’
(care – careful).

• The suffix -less is used after a noun to form an adjective which means ‘not having’
(end – endless).

B. Complete the sentences using the correct form of the words in capitals.
