New words can often be made by adding a suffix to the end of a root word.
For example:
quick + ly = quickly
wonder + ful = wonderful
Sometimes different suffixes can be added to the same root word to make several new words.
For example:
wonderful wonderment
careful careless
kindly kindness
In this activity, you can investigate which words can be made by adding suffixes to root words. You may need to use a dictionary to check whether the words exist or not!
