The subjunctive form is not considered a verbal because it is not used to express action or state. Instead, it is used to express hypothetical or unreal situations, wishes, recommendations, or demands. Verbal forms, on the other hand, are verb forms that function as verbs in a sentence and express action or state. Examples of verbal forms include participles, gerunds, and infinitives, which all have verbal characteristics and can function as nouns, adjectives, or adverbs in a sentence.
