Verb Forms: Regular and Irregular

Verbs are the action words in a sentence. They tell us what the subject is doing or being. In English, verbs change their form to indicate tense (past, present, future), number (singular, plural), and person (first, second, third). We primarily focus on how verbs change to show past actions, which leads to the concepts of regular and irregular verbs.

Regular Verbs

Regular verbs form their past tense and past participle by adding '-d' or '-ed' to the base form. These verbs follow a predictable pattern.

Examples:

• Base Form: walk → Past Tense: walked → Past Participle: walked
• Base Form: play → Past Tense: played → Past Participle: played
• Base Form: love → Past Tense: loved → Past Participle: loved
• Base Form: jump → Past Tense: jumped → Past Participle: jumped

When the base form ends in 'e', we just add 'd'. For verbs ending in a consonant preceded by a single vowel, we often double the final consonant before adding '-ed' (e.g., stop → stopped). For verbs ending in 'y' preceded by a consonant, we change 'y' to 'i' and add '-ed' (e.g., study → studied).

Irregular Verbs

Irregular verbs do not follow the standard '-d' or '-ed' rule. Their past tense and past participle forms are learned through memorization. There are many irregular verbs in English, and they are very common.

Examples:

• Base Form: go → Past Tense: went → Past Participle: gone
• Base Form: see → Past Tense: saw → Past Participle: seen
• Base Form: eat → Past Tense: ate → Past Participle: eaten
• Base Form: come → Past Tense: came → Past Participle: come
• Base Form: be → Past Tense: was/were → Past Participle: been

It is crucial to learn the principal parts of common irregular verbs: the base form (infinitive), the simple past tense, and the past participle. The past participle is used with auxiliary verbs like 'have', 'has', 'had', 'be', 'is', 'am', 'are', 'was', 'were' to form perfect tenses and passive voice.

Table of Common Irregular Verbs:

Infinitives

An infinitive is the base form of a verb, usually preceded by 'to'. It can function as a noun, an adjective, or an adverb in a sentence. Infinitives do not change form based on tense or number.

The Infinitive Form

The most common form is the "to-infinitive," which includes 'to' followed by the base verb. For example, 'to eat', 'to run', 'to be'.

There is also the "bare infinitive," which is the base form of the verb without 'to'. It is used after certain verbs (like 'make', 'let', 'help') and modal verbs (like 'can', 'will', 'should').

Functions of Infinitives

1. As a Noun: Infinitives can act as the subject or object of a sentence.

• Subject: To err is human.
• Object: She wants to learn Spanish.
• Complement: His goal is to win the championship.

2. As an Adjective: Infinitives can modify nouns or pronouns.

• There is a lot of work to do. (modifies 'work')
• She is the person to ask for help. (modifies 'person')

3. As an Adverb: Infinitives can modify verbs, adjectives, or other adverbs, often explaining the reason or purpose.

• He studies hard to pass the exam. (explains why he studies)
• I am happy to see you. (explains why I am happy)
• This is too difficult to understand. (modifies 'difficult')

Common Verbs Followed by Infinitives

Many verbs are followed by a to-infinitive. Some common ones include: want, wish, hope, decide, plan, learn, agree, promise, refuse, offer, seem, appear, need, expect, manage, pretend.

Example:

They decided to go to the park. She hopes to see you soon. He offered to help me.

Common Verbs Followed by Bare Infinitives

Verbs like 'make', 'let', and 'help' are often followed by a bare infinitive.

• The teacher made him repeat the sentence. (NOT 'to repeat')
• Let me know your decision. (NOT 'to know')
• She helped me carry the bags. (or 'helped me to carry')

Infinitives after Modal Verbs

Modal verbs (can, could, may, might, will, would, shall, should, must) are always followed by a bare infinitive.

• You can swim very well.
• She should study more.
• He must go now.

Gerunds

A gerund is a verb form ending in '-ing' that functions as a noun. Like infinitives, gerunds do not change form and can act as the subject, object, or complement of a sentence.

The Gerund Form

The gerund is formed by adding '-ing' to the base form of a verb. For example, 'swimming', 'reading', 'eating'.

Functions of Gerunds

1. As a Subject:

• Swimming is good exercise.
• Reading keeps the mind active.
• Smoking is prohibited here.

2. As an Object: A gerund can be the direct object of a verb.

• I enjoy listening to music.
• She hates waking up early.
• They finished painting the house.

3. As a Complement: A gerund can follow a linking verb (like 'be', 'seem', 'become').

• My favorite hobby is gardening.
• His main problem is forgetting names.

4. After Prepositions: Gerunds are always used after prepositions (e.g., in, on, at, for, about, after, before, of, without).

• Thank you for helping me.
• She is good at singing.
• He left without saying goodbye.
• We talked about moving to a new city.

Verbs Followed by Gerunds

Certain verbs are typically followed by a gerund. Some common ones include: enjoy, finish, avoid, mind, suggest, quit, practice, admit, deny, postpone, risk, consider, keep, miss, imagine.

Example:

He admitted stealing the money. They suggested meeting at the cafe. I miss travelling.

Distinguishing Gerunds from Present Participles

Both gerunds and present participles end in '-ing'. The key difference is their function:

• Gerund: Acts as a noun.
• Present Participle: Acts as an adjective or part of a continuous verb tense.

Example:

• Gerund: Running is fun. (Subject)
• Present Participle: The running water was cold. (Adjective modifying 'water')
• Present Participle: He is running a marathon. (Part of the present continuous tense)

Participles

Participles are verb forms that function as adjectives or as part of verb phrases. There are two main types of participles in English: the present participle and the past participle.

1. Present Participle

The present participle is formed by adding '-ing' to the base form of the verb (e.g., walking, eating, speaking). It can be used in several ways:

• As an Adjective: It describes a noun or pronoun.
• The crying baby needs attention.
• It was an exciting movie.
• I saw a flying bird.
• In Continuous Tenses: It is used with auxiliary verbs (be, am, is, are, was, were) to form the present continuous, past continuous, future continuous, etc.
• She is reading a book. (Present Continuous)
• They were playing outside. (Past Continuous)
• We will be travelling next week. (Future Continuous)
• In Participial Phrases: A phrase consisting of a participle and its modifiers or complements, acting like an adjective.
• Having finished his work, he went home. (Past participial phrase)
• Running quickly, he caught the bus. (Present participial phrase)

2. Past Participle

The past participle is the form of the verb used to express completed actions. For regular verbs, it is the same as the past tense form (ending in '-ed'). For irregular verbs, the past participle form must be memorized (e.g., eaten, seen, gone, broken).

Past participles are used in the following ways:

• In Perfect Tenses: Used with auxiliary verbs (have, has, had) to form the present perfect, past perfect, future perfect tenses.
• I have finished my homework. (Present Perfect)
• She had seen that movie before. (Past Perfect)
• They will have arrived by now. (Future Perfect)
• In the Passive Voice: Used with forms of the verb 'to be' (am, is, are, was, were, been) to form the passive voice.
• The letter was written by him.
• The cake is baked fresh every day.
• Mistakes were made.
• As an Adjective: It can describe a noun or pronoun, often indicating a state resulting from an action.
• The broken window needs repair.
• I read an interesting book. (Note: 'interesting' is present participle used as adjective)
• He felt tired after the long journey. ('tired' is past participle used as adjective)
• The painted walls looked fresh.
• In Participial Phrases: Similar to present participial phrases, these phrases modify nouns or pronouns.
• Broken by the storm, the tree fell down.
• Known for his honesty, he was trusted by everyone.

Question Tags

Question tags are short questions added to the end of a statement. They are used to confirm information or to encourage agreement. They are very common in spoken English.

Structure of a Question Tag

A question tag consists of an auxiliary verb (or modal verb) and a pronoun. The auxiliary verb used in the tag is usually the same as the one used in the statement. If there is no auxiliary verb in the statement (i.e., it uses a simple present or simple past verb), we use 'do', 'does', or 'did' in the tag.

Rules for Forming Question Tags

1. Positive Statement, Negative Tag: If the statement is positive, the question tag is usually negative.

• It is a beautiful day, isn't it?
• You like coffee, don't you?
• She can swim, can't she?
• They went home, didn't they?

2. Negative Statement, Positive Tag: If the statement is negative, the question tag is usually positive.

• It isn't raining, is it?
• You don't speak French, do you?
• He won't be late, will he?
• We haven't seen her, have we?

3. Pronoun in the Tag: The pronoun in the tag must refer to the subject of the statement. It cannot be a noun.

• Ravi is here, isn't he? (NOT 'isn't Ravi?')
• The dogs are barking, aren't they? (NOT 'aren't the dogs?')

4. Auxiliary/Modal Verbs: Use the same auxiliary or modal verb from the statement.

• She has finished, hasn't she?
• You could help me, couldn't you?
• They will come, won't they?

5. Simple Present/Past Tense: Use 'do', 'does', or 'did' if the statement uses a simple present or simple past verb without an auxiliary.

• You live here, don't you?
• He works late, doesn't he?
• She played well, didn't she?

Special Cases

• 'I am': The tag for 'I am' is usually 'aren't I'.
• I am late, aren't I?
• Negative words in the statement: Statements with words like 'never', 'hardly', 'scarcely', 'rarely', 'seldom' are considered negative, so they take a positive tag.
• He never complains, does he?
• She hardly works, does she?
• 'Let's': For 'Let's' (Let us), the tag is always 'shall we'.
• Let's go, shall we?
• Imperatives (Commands/Requests): For positive or negative imperatives, the tag is usually 'will you' or 'won't you'.
• Open the door, will you?
• Don't be late, will you? (or won't you?)
• 'There is/are': Use 'there' in the tag.
• There is a book, isn't there?
• There are many people, aren't there?
• 'This/That': Use 'it' in the tag.
• This is your car, isn't it?
• 'These/Those': Use 'they' in the tag.
• Those are his books, aren't they?
