Word Families

Here's an example of what we call a word family in this lesson: 


	jump
	jumps
	jumping
	jumped
	jumper
A word family includes all the variations of the word which can be obtained by changing the ending suffix to the root word.

Here's another example: 


	grow
	grows
	growing
	growth
	grown
	grower
Notice that "grew" is not on the list since the root word must be changed and only forms of the word with a suffix added onto the root word are part of the word family.
