Final answer:
The statement is true as verbs represent both actions and states of being, critical for conveying time and forming phrases with subjects and auxiliaries in different tenses.
Step-by-step explanation:
True, a verb is a word that not only shows action but also a state of being or description. Verbs come in various forms and are essential in forming verb phrases with the assistance of auxiliaries such as 'will' or 'shall'. They are the crux of sentence structure, pairing with subjects to express what the subject is doing or experiencing. Verbs are also marked by their ability to change form according to tense, indicating if the action or state is in the past, present, or future. Furthermore, verbs like 'to be', which express a state of existence rather than an active action, follow specific sentence patterns involving adverbials, adjectives, or noun phrases.
