Which verb is the italicized word?

The baby is (this is italicized) becoming louder with each waking moment.

1. action verb
2. helping verb
3. linking verb
4. transitive verb

2?

Right.

The verb "is" in the sentence is a linking verb.

To determine the verb in the sentence, you need to identify the word that expresses the action or state of being. In the given sentence, the italicized word is "becoming." By evaluating the different options, we find that "becoming" in this context is functioning as a linking verb.

Linking verbs do not denote action but instead connect the subject of the sentence with a word or phrase that renames or describes it. In this case, "becoming" connects the subject "baby" with the adjective "louder."

Therefore, the correct answer is 3. linking verb.
