Correcting Omitted -s or -ed Endings

Spoken English is much less formal than standard written English. If you omit -s endings when you speak, be careful to include them when you write.

CORRECT:
My sister walks her dog every day.
Her dog barks at everyone.

INCORRECT::
My sister walk her dog every day.
Her dog bark at everyone.

Many speakers also leave off -ed endings, especially when those endings are difficult to pronounce or to hear. The following sentences have correct verb endings:

CORRECT:
My sister used to walk her dog every day.
Now I am supposed to walk it.

INCORRECT::
My sister use to walk her dog every day.
Now I am suppose to walk it.

When you use the following words, be careful that you do not omit -ed endings when they are needed:

asked	fixed	pronounced
basked	frightened	risked
concerned	improved	supposed to
developed	prejudiced	used to

Click the correct sentence. I am supposed to have my term paper finished next week. I am suppose to have my term paper finished next week.
