Verb classification is the process of categorizing verbs based on their grammatical and semantic properties. Common classifications include transitive verbs, which require a direct object, and intransitive verbs, which do not. Additionally, verbs can be classified as linking verbs, which connect the subject to a subject complement, or auxiliary verbs, which help form different tenses or moods. Another way to classify verbs is by their aspect, such as perfect or progressive, which indicate the timing and nature of the action. Verbs can also be categorized by their regularity; regular verbs follow a consistent pattern in their conjugation, while irregular verbs do not. Understanding these classifications helps in mastering verb usage in language.
