Consonant Alternation

A suffix is a word part that comes at the end of a base word and changes the word’s meaning. Adding a suffix may change the sound of the consonant in the base word. 

For example, in the word sign, the consonant g is silent. 
When you add the suffix -al to make signal, the g is no longer silent. 

This kind of change is called consonant alternation.

A. Read each pair of words. Circle the pair that has consonant alternation. Then write the letter that has a change in sound.

1. crumb/crumble                 flex/flexible         ................
2. love/lovable                     design/designate   ................
3. refuse/refusal                   office/official        
................
4. create/creation                 propose/proposal   
................
5. public/publicity               suburb/suburban
