What type of verbs express a state of being or existence?

Linking verbs are designed to connect the subject of a sentence with a subject complement, which can be a noun, pronoun, or adjective that describes or identifies the subject. These verbs serve the crucial function of expressing a state of being or existence. Common examples of linking verbs include "is," "am," "are," "was," and "were."

In contrast, action verbs signify active processes and behaviors, representing actions performed by the subject, rather than states of being. Transitive verbs require a direct object to complete their meaning, focusing on actions that transfer from the subject to the object. Intransitive verbs do not take a direct object and also emphasize actions rather than states or conditions. Therefore, linking verbs uniquely fulfill the role of conveying existence or conditions, making them the correct choice for this question.
