The Verb (The Action Word)

Conceptual Definition

A Verb is a word used to describe an action, state, or occurrence. It is the most indispensable part of a sentence; indeed, a sentence cannot exist without at least one verb. Verbs indicate not only what the subject is doing but also the time (Tense) at which the action occurs.

Classifications of Verbs

Action Verbs (Main Verbs)

These express physical or mental activities.

Physical: Run, eat, swim, shout.

Mental: Think, believe, guess, wonder.

Transitive and Intransitive Verbs

This distinction is vital for advanced grammar and passive voice

Transitive Verbs: Require a direct object to complete their meaning.

Example: She wrote (Verb) a letter (Object).

Intransitive Verbs: Do not require an object to make sense.

Example: The baby slept. (No object needed).

Linking Verbs (Copular Verbs)

These do not express action. Instead, they “link” the subject to a word that describes or renames it (the Subject Complement).

Common Linking Verbs: Is, am, are, was, were, seem, become, feel, appear.

Example: The cake tastes delicious.

Auxiliary (Helping) Verbs

These are used together with a main verb to express tense, mood, or voice.

Primary Auxiliaries: Be (is/am/are), Do, Have.
Modal Auxiliaries: Can, could, shall, should, will, would, may, might, must. (These express possibility, necessity, or permission).

Verb Forms (The Principal Parts)

Every verb has different forms to indicate the timing of the action:

Base Form (V1): Eat, Go, Play
Past Simple (V2): Ate, Went, Played
Past Participle (V3): Eaten, Gone, Played
Present Participle (V4): Eating, Going, Playing (The -ing form)

Finite vs. Non-Finite Verbs

Finite Verbs: Change their form according to the subject and tense. (He plays / They play.)
Non-Finite Verbs: Do not change based on the subject. These include Infinitives (to play), Gerunds (playing), and Participles.

Essential Rules for Verbs

Subject-Verb Agreement:

A singular subject requires a singular verb, and a plural subject requires a plural verb.

Stativity

Some verbs (Stative Verbs) like love, know, hate, believe are generally not used in the continuous (-ing) form.

Confusion with "Lie" and "Lay"

Lie (Intransitive): To rest or recline. (Lie down.)

Lay (Transitive): To put something down. (Lay the book on the table.)
