Verb Usage
Common errors with verb forms
One common error occurs with –s endings.
Use the –s form of a verb when the noun is third-person singular and the action occurs in the present.
The singer asks [not ask] for a glass of water.
Another common error occurs with –ed endings.
Sometimes this happens with certain words whose –ed endings are not always pronounced in casual
speech. However, the –ed ending must be included in written form. Some of these words include
“supposed,” “used,” “asked,“ ”discussed,“ ”mixed,“ and “walked.”
I used to work at the local grocery store.
Janice was lost, so she asked the stranger for directions.
Sometimes an -ed error happens with the past participle form of a verb. When the verb is used with a
helping verb such as be or have, you need the past participle (the -d or –ed) form of the verb.
He is concerned [not concern] about his grades.
I have watched [not watch] many sunsets.
Another error occurs with improper infinitive forms.
An infinitive is the plain form of the verb with the word to in front of it: to run, to know, to be.
Infinitives can function in many ways in a sentence, but by themselves they are not the main verb and
should not have additional endings on them such as –s, -ed, or –ing.
I wanted to watch [not to watched] my favorite show, but the power went out.
A final error occurs with the irregular verbs “to be” and “to have.”
Be sure to use the proper form of the verb for the tense you need:
To Be: Present Tense: I am you are he, she, it is we are you are they are
Past Tense: I was you were he, she, it was we were you were they were
To Have: Present Tense: I have you have he, she, it has we have you have they have
Past Tense: I had you had he, she, it had we had you had they had
Many verbs express action. (feel, shout, walk, grow, have, consider, study) Ask, “Who or what is doing what in
the sentence?” The “doing what” is the verb.
Other verbs show a state of being. (am, is, are, was, were) Remember these words; they are always verbs.
Sometimes verbs occur in phrases. (Examples: has jumped; should have known; is running; will try)
Subjects can have more than one verb. (She enjoys downtown shopping but hates traffic.)
