III. Pronunciation (20'')

 Stress in words starting with un- and im-

. Explain to Ss that the prefixes un- and im- are used to make adjectives (and adverbs) negative. Explain to them that when these prefixes are added, the stress of the new word does not normally change. Give some examples. When we add the prefix un- or im-  meaning ‘not’ ) to a root word, the stress of the word does not normally change.

Example:    ‘friendly  -> un’friendly

                   ‘probable  -> im’probable

Note: When we add the prefix un- or im- to a one-syllable word, the stress falls on the root word.

Example:    fair  -> un’fair

                  Pure  -> im’pure
