Pronunciation:
Stress in words starting with un- and im-


When we add the prefx 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
