The -ed Suffix

A common suffix which you will see added to the end of many words is -ed. Usually -ed is used to create a verb in the past tense. Here are some examples: 


	VERB			VERB with -ED

	add			added
	use			used
	drop			dropped
	pull			pulled
	scratch			scratched
	yell			yelled
        try			tried
You will notice that you don't simply add -ed to the end of each word. In fact, if you study this list carefully you will notice four different rules for adding -ed. 

  RULE ONE: Just add -ed.  Example: pull + ed = pulled

  RULE TWO: Just add d.    Example: use + ed = used

  RULE THREE: Double the last letter and add -ed. Example: drop + ed = dropped

  RULE FOUR: Drop the y and add -ied. Example: try + ed = tried
