Grammar 17 Main Verbs and Helping Verbs
Verbs have four principal parts that are used to form all tenses.
PRINCIPAL PARTS OF THE VERB CALL
Base Form- call
Present Participle- calling
Past Form- called
Past Participle- called
A 'helping verb' helps the 'main verb' tell about an action or make a statement. A verb phrase consists of one or more helping verbs followed by a main verb.
The girl is 'calling' her parents. (Is is the helping verb, and the present participle calling is the main verb. Together they form a verb phrase.)
The most common helping verbs are be, have, and do. Forms of the helping verb be include am, is, and are in the present and was and were in the past. They combine with the present participle of the main verb. Forms of the helping verb have include have and has in the present and had in the past. They combine with the past participle form of a verb.
We have 'explored' this cave. (Have is the helping verb, and the past participle explored is the main verb. Together they form a verb phrase.)
Exercise 1 Identify the participle. Select whether it is a
