Pronunciation

Stress in words starting with un- and im-

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

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