Worksheet Overview

QUESTION 1 of 10

The suffix -ify can be used to change nouns and adjectives into verbs.

solid + ify = solidify

 

However, sometimes the root word changes before the suffix is added.

peace + ify = pacify

horror + ify = horrify

 

The suffix -ate can also change nouns and adjectives into verbs, but again the root word often changes as well.

medical + ate = medicate

pollen + ate = pollinate

 

In this worksheet you can practise adding suffixes to words where the root word also needs to be changed.

Match up the root nouns and adjectives on the left with the verbs ending in -ify on the right.

 

Pay attention to the spellings as you may need them in later questions.
