A prefix is added to the start of a word and a suffix to the end. They change the meaning: un- means not (unhappy), re- means again (redo), -ful means full of (hopeful) and -less means without (careless).
What your child will learn
- Know the meanings of the prefixes un-, re-, dis-, pre- and in-
- Know the meanings of the suffixes -ful, -less, -ness, -er and -ly
- Use prefixes and suffixes to work out new words
Word-building blocks
Once children know a handful of prefixes and suffixes, they can work out hundreds of new words on their own. “Unbreakable” is un + break + able: not able to be broken.
