1. The Mysterious Sounds of Suffix -ed
By Miss Quick

2. To answer that you need to know what a root or base word is!
Simply put-a root or a base word is a word that has meaning
A suffix- is a letter or a group of letters added to the end of a word to change how the word is used
What is a suffix?
3. How does it change a baseword?
It changes it to the past tense
Read these words from The Revealers to find out what sound it makes?
shadowed
brutalized
sauntered
arced
hoisted
What do you know about ed?
4. Take a look at these words from to see if you can figure out the rule:
Meltedburnedbanded
Kissedsmelledasked
Peeledgrilledfilmed
Seededdraftedlicked
Why? How? When?What the.?
5. Suffix ed makes the sound:
/d/ after a voiced sound
/t/ after an unvoiced sound
/ed/or /id/ after the letter t or d
So What is the RULE ALREADY!!!
6. voiced=vibrates your vocal cords
/l/, /m/, /n/,/b/
Thrilled, trimmed, pinned, rubbed
Notice any relationship b/t the sound ed makes and the sound the final letter in the baseword makes?
Unvoiced=does not vibrate your vocal cords
/s/, /k/, /p/, /f/
Kissed, asked, limped, golfed
Notice any relationship b/t the sound ed makes and the sound the final letter in the baseword makes?
Voiced/Unvoiced!What does that mean?
7. Lets take another look at the suffix ed words from The Revealers:

Suffix ed practice
8. Prizes if you can remember!!!
What is that RULE again?
9. hopefulsafelysmokeless
carefultimelypureness
shapelesspridefulfineness
Ahh, the basewords all in SILENT E!
What do you notice about all of these words:
10. paralyzedexaggeratedbrutalized
scrutinizedconceivabledissipated
rampaginghumiliatingrevoked
persecutedcascadingsquabbling
What do all of these words from The Revealers have in common?
11. paralyzedexaggeratedbrutalized
paralyzeexaggeratebrutalize
scrutinizedconceivabledissipated
scrutinizeconceivedissipate
rampaginghumiliatingrevoked
rampagehumiliaterevoke
persecutedcascadingsquabbling
persecutecascadesquabble
Here is a BIG hint!
12. Hey!What happened to the E when the suffix was added?Can you just drop it like that?
paralyze + ed = paralyzed
exaggerate + ed=exaggerated
brutalize + ed= brutalized
13. hopefulsafelysmokeless
How come the E isnt dropped in these words?
Lets compare the words above to these and see if we can figure it out!
scrutinizedconceivabledissipated
Wait a minutethose first words
14. hope+ful=hopeful
safe+ly=safely
smoke+less=smokeless
scrutinize+ed=scrutinized
conceive+able=conceivable
dissipate+ed=dissipated
Still cant figure it out?Lets look at them this way:
15. If you havent figured it out yet, this will DEFINITELY help!
16. So the RULE is.
If the baseword ends in silent E, drop the E when adding a vowel suffix!
ed, ing, able, er, y
17. But WHY, you ask?
1. How would you read the following words if you didnt drop the E?
shapeingglideertimeed
serveedhideingtapeed
2. It doesnt look right!
3. It goes against what we have learned about two vowels go walking
4. It has to do with syllable division, but that is a Quick English Lesson for another time!
18. A little more practice
19. If you can remember this rule when I introduce the next Quick English lesson
There will be more prizes!!!
And guess what?
