Step-by-step explanation:
Am, Is, Are, Was, Were are known to be auxiliary verbs. Auxiliary verbs are verbs that are used to help or assist the main verbs in a sentence. They are also known as helping verbs.
Was and Were are the past tense of is, am and are. Was is used for singular objects while were is used for plural objects.
“was” is used with "I, he, she" and “were” is used with "you, we and they"
