Parts of Speech – Verbs – Grammar Course

What is a verb?

A verb is a word that expresses an action, occurrence, or state of being. Verbs are essential to predicate structure and indicate time (tense), aspect, mood, and sometimes voice.

Key functions: show action (run), show state (be), link subject to complement (be, become), or help form tenses and moods (have, will, can).

Major verb categories (overview)

Action verbs

Describe physical or mental actions.

Examples: run, think, write — “She writes a letter.”

Linking (copular) verbs

Connect subject with a subject complement (state or identity).

Examples: be, seem, become — “He is happy.”

Auxiliary (helping) verbs

Combine with main verbs to form tense, voice, aspect, mood.

Examples: have, be, do, will, can — “They have finished.”

Modal verbs

Express necessity, possibility, permission, ability, or obligation.

Examples: can, could, may, might, must, should — “You should study.”

Transitive vs. Intransitive

Transitive verbs take a direct object; intransitive verbs do not.

Transitive: “She ate an apple.” Intransitive: “He laughed.”

Regular vs. Irregular

Regular verbs form past/past participle with -ed; irregular verbs use other patterns.

Regular: walk — walked — walked. Irregular: go — went — gone.

Detailed verb types with examples

1. Action verbs

Describe what someone or something does (physical or mental).

Physical: run, jump, cut — “They cut the ribbon.”
Mental: think, believe, remember — “I remember the address.”

2. Linking (copular) verbs

Link subject to adjective or noun that describes/identifies it. Common linkers: be, seem, become, appear, feel.

“The soup smells good.” — smells links soup to quality.

3. Auxiliary (helping) verbs

Used with main verbs to create tense, aspect, passive voice, or questions/negations.

Perfect aspect: have + past participle — “She has eaten.”
Progressive aspect: be + present participle — “They are running.”
Passive voice: be + past participle — “The book was written.”
Do-support: do/does/did for questions/negatives — “Do you like it?” “She did not come.”

4. Modal verbs

Express modality: ability, permission, possibility, necessity, obligation.

“Can” (ability): “She can swim.”
“May” (permission/possibility): “May I enter?” / “It may rain.”
“Must” (obligation): “You must wear a seatbelt.”

5. Transitive and intransitive verbs

Transitive: require a direct object. Intransitive: do not take a direct object. Some verbs can be both (ambitransitive).

Transitive: “He reads the book.”
Intransitive: “She sleeps.”
Ambitransitive: “He sings a song.” / “He sings every day.”

6. Regular and irregular verbs

Regular: predictable past/past-participle -ed. Irregular: various patterns—must be learned.

Regular: “talk — talked — talked.”
Irregular: “see — saw — seen.”

7. Phrasal verbs

Verb + particle(s) (preposition/adverb) that form idiomatic meanings. Important in spoken/written English.

“Look up” (search): “Look up the word.”
“Give up” (quit): “She gave up smoking.”

8. Stative vs. Dynamic verbs

Stative verbs describe states (emotion, possession, perception) and usually not used in progressive aspect. Dynamic verbs describe actions or processes and can be progressive.

Stative: love, own, know — “I know the answer.” (not “I am knowing…”)
Dynamic: write, run, grow — “She is writing a letter.”

9. Causative verbs

Express that one person causes another to do something or causes a change of state (make, have, get, let).

“She made him apologize.” — causative with direct object + base verb.
“I had the car washed.” — causative with object + past participle.

10. Perfect, progressive and perfect-progressive aspects (form categories)

These are verb constructions (using auxiliaries) that express time and aspect.

Perfect: “They have left.”
Progressive: “He is studying.”
Perfect-progressive: “She has been working for three hours.”

11. Finite vs. Non-finite verbs

Finite verbs show tense, person, number and can function as the main verb in clauses. Non-finite verbs do not show tense and cannot be the clause’s finite verb: infinitives, gerunds, participles.

Finite: “He writes every day.”
Non-finite: “To write is useful.” (infinitive) — “Writing improves skill.” (gerund) — “Written by her, the letter arrived.” (past participle)

Quick classroom activities

Identify: Give sentences and ask students to label verb type (action/linking/modal, transitivity).
Transform: Change active to passive or simple to perfect progressive.
Sort: Provide verbs cards and have students group regular/irregular, transitive/intransitive, stative/dynamic.
Phrasal verb matching: Match phrasal verbs to meanings and use them in sentences.

Common errors to highlight

Incorrect tense with time markers: “I have seen him yesterday.” → “I saw him yesterday.”
Using stative verbs in progressive: “I am knowing” → “I know.”
Confusing transitive/intransitive patterns: “He broke” vs “He broke the vase.”
