Finite and Non-finite Verbs: Finite verbs are verbs that show tense, number, and person. They can stand alone as the main verb in a sentence. Non-finite verbs do not show tense, number, or person. They cannot stand alone as the main verb in a sentence.

Regular and Irregular Verbs: Regular verbs follow a predictable pattern when forming their past tense and past participle forms. Irregular verbs do not follow a predictable pattern and must be memorized.

Transitive and Intransitive Verbs: Transitive verbs require a direct object to complete their meaning. Intransitive verbs do not require a direct object.

Auxiliary Verbs: Auxiliary verbs, also known as helping verbs, are used with main verbs to create different verb tenses, moods, and voices.

Modal Auxiliary Verbs: Modal auxiliary verbs express possibility, necessity, ability, permission, and other related meanings. They include will, shall, should, would, can, could, may, might, must, and ought to.

Infinitives: Infinitives are the base form of a verb, usually preceded by the word “to.” They can function as nouns, adjectives, or adverbs.

Participles: Participles are verb forms that can function as adjectives. There are two types: present participles (ending in -ing) and past participles (usually ending in -ed or -en).

Stative Verbs: Stative verbs, also known as state verbs, describe a state or condition rather than an action. They are not usually used in continuous tenses.

Phrasal Verbs: Phrasal verbs are verb phrases that consist of a main verb and one or more particles (prepositions or adverbs). The meaning of the phrasal verb is often idiomatic and cannot be deduced from the meanings of its individual parts.

Light Verbs: Light verbs are verbs that have little semantic content on their own and rely on a noun or adjective to give them meaning. Examples include “make,” “take,” and “do.”

Linking Verbs: Linking verbs connect the subject of a sentence to a noun, pronoun, or adjective that renames or describes the subject. Common linking verbs include “be,” “seem,” and “become.”
