When is a verb not a verb? When it is a verbal.
You remember that in English there are only four forms of each verb: the present, the present participle, the past, and the past participle. Sometimes when you see these forms in a sentence, they are not actually being used as verbs.Definition: A verbal (or non-finite verb) is a verb form that is not being used as a verb. Verbals can act as nouns, adjectives, or adverbs. There are three types of verbals: the present participle, the past participle, and the infinitive, which is formed by putting to in front of the present tense form. (A verb being a verb is called a finite verb.)

Verbal: Tired out by all that dancing, I went home and collapsed. (past participle)
Verb: We always sing the National Anthem at the ball game.
Verbal: I really like to sing. (to + present = infinitive)
