Verb: Definition, Role, and Types

Verb: Definition, Role, and Types

A verb is a word or a phrase that expresses an action, state, or occurrence. It is an essential component of a sentence, forming the main part of the predicate.

Role of Verbs in a Sentence

Every complete sentence must have a verb. Verbs can indicate:

• Actions: read, walk, run, eat, learn, etc.
• States: be, exist, stand, etc.
• Occurrences: happen, become, etc.

Examples:

• He is a good man. (State)
• We learn from the Web. (Action)
• She speaks English fluently. (Action)
• Rimi is thinking about the incident. (Occurrence)

Verbs change based on tense (past, present, future), person (first, second, third), number (singular, plural), and voice (active, passive).

Types of Verbs

Verbs fall into two broad categories:

1. Principal (Lexical/Main) Verbs
2. Auxiliary (Helping) Verbs

1. Principal or Lexical Verbs

These verbs can function independently without requiring assistance from other verbs.

Examples:

• He is a singer.
• She does her job.
• They have many problems.

Types of Principal Verbs:

a) Transitive Verbs

Transitive verbs require a direct object to complete their meaning.

Examples:

• She reads the book. (Object: "the book")
• He gave me a mobile phone. (Objects: "me" and "a mobile phone")

To identify a transitive verb, ask "What?" or "Whom?" after the verb. If there is an answer, the verb is transitive.

b) Intransitive Verbs

Intransitive verbs do not require a direct object.

Examples:

• She reads. (No object)
• The birds are flying.
• The sun set.

2. Auxiliary (Helping) Verbs

These verbs assist the main verb in forming different tenses, voices, or moods.

Examples:

• He is singing a song.
• She has completed the assignment.
• They are facing difficulties.

a) Primary Auxiliaries

These include be, am, is, was, are, were, been, being, have, has, had, having, do, does, did.

Examples:

• I am doing the job. (Present continuous)
• She was sleeping at that time. (Past continuous)
• They have completed the task. (Present perfect)

• Shall we start the game? (Question)

Finite and Non-finite Verbs

1. Finite Verbs

A finite verb changes according to tense, number, and person. It must have a subject.

Examples:

• He makes me proud.
• I will write a book.
• The honey tastes sweet.

2. Non-finite Verbs

A non-finite verb does not change according to tense, number, or person. It cannot act as the main verb.

Types of Non-finite Verbs:

i. Infinitives

Infinitives are formed using to + base form of the verb.

Examples:

• He likes to play football.
• She is too late to go.
• They came here to hear the news.

Bare Infinitives (without "to") appear after certain verbs like bid, let, make, need, dare, see, and hear.

Examples:

• Let her go.
• You need not leave the place.

ii. Gerunds

A gerund is formed by adding -ing to the base verb. It functions as a noun.

Examples:

• Swimming is good for health.
• I saw her crying.
• Seeing is believing.

iii. Participles

Participles act as adjectives.

🔹 Present Participle (-ing form):

• A running bus is dangerous.
• The boiling water is hot.

🔹 Past Participle (-ed, -d, -t forms):

• They have invited him to the party.
• A faded flower attracts none.

📌 Note:

• Gerunds act as nouns. Example: Swimming is fun.
• Present participles act as adjectives. Example: A swimming snake bit him.
