Fascinating Fact:

The word “care” becomes “careless” or “careful,” proving suffixes can totally change a personality.

In KS2 English, pupils learn how suffixes are added to the ends of root words to change their meaning or word class. For example, adding “ness” turns “happy” into “happiness,” and “ful” turns “hope” into “hopeful.” Understanding suffixes helps pupils expand their vocabulary and write more creatively.
