What is a Verb?

A verb is a word that describes an action, occurrence, or state of being. It’s the core of a sentence’s predicate, conveying what the subject does or is.

Without a verb, a group of words is not a complete sentence. Verbs indicate time (present, past, future), possibility, necessity, and other nuances of meaning.

They are essential for conveying information and expressing ideas effectively.

Understanding verbs involves recognizing their various forms and functions. This includes identifying the tense, voice, and mood of a verb, as well as its relationship to the subject and other words in the sentence.

Mastering verbs is fundamental to writing clear, grammatically correct sentences.

Structural Breakdown of Verbs

Verbs can be broken down into several key components:

  • Base Form: The simplest form of the verb (e.g., walk, eat, be).
  • Past Tense Form: Indicates an action or state completed in the past (e.g., walked, ate, was/were).
  • Past Participle Form: Used with auxiliary verbs to form perfect tenses (e.g., walked, eaten, been).
  • Present Participle Form: Used with auxiliary verbs to form continuous tenses (e.g., walking, eating, being).
  • Third-Person Singular Present Form: Used when the subject is a singular noun or pronoun (e.g., walks, eats, is).

Understanding these forms is crucial for constructing grammatically correct sentences and avoiding common verb errors. The correct form of the verb must align with the tense, subject, and context of the sentence.

Types of Verbs

Verbs can be classified into several types based on their function and how they relate to other elements in the sentence.

Action Verbs

Action verbs describe what the subject of the sentence does. They can be either transitive or intransitive.

  • Transitive Verbs: Take a direct object (e.g., She kicked the ball).
  • Intransitive Verbs: Do not take a direct object (e.g., He slept soundly).

Linking Verbs

Linking verbs connect the subject of a sentence to a noun or adjective that describes or identifies the subject. Common linking verbs include be (is, am, are, was, were, been, being), become, seem, appear, look, feel, taste, smell, and sound.

Examples:

  • She is a doctor.
  • The soup tastes delicious.
  • He seems happy.

Helping Verbs

Helping verbs (also known as auxiliary verbs) are used with a main verb to form a verb phrase. They help to express tense, mood, or voice. Common helping verbs include be, have, do, can, could, may, might, must, shall, should, will, and would.

Examples:

  • I am studying.
  • They have finished.
  • She will arrive soon.

Verb Tenses

Verb tenses indicate when an action or state of being occurs. There are twelve main verb tenses in English, divided into three categories: simple, perfect, progressive, and perfect progressive.

Simple Tenses

  • Simple Present: Describes habitual actions, general truths, or current states (e.g., I walk to school every day).
  • Simple Past: Describes actions completed in the past (e.g., I walked to school yesterday).
  • Simple Future: Describes actions that will happen in the future (e.g., I will walk to school tomorrow).

Perfect Tenses

  • Present Perfect: Describes actions that started in the past and continue to the present or have a result in the present (e.g., I have walked to school for five years).
  • Past Perfect: Describes actions completed before another action in the past (e.g., I had walked to school before it started raining).
  • Future Perfect: Describes actions that will be completed before a specific time in the future (e.g., I will have walked to school for ten years by 2030).

Progressive Tenses

  • Present Progressive: Describes actions happening now or around now (e.g., I am walking to school right now).
  • Past Progressive: Describes actions in progress at a specific time in the past (e.g., I was walking to school when I saw her).
  • Future Progressive: Describes actions that will be in progress at a specific time in the future (e.g., I will be walking to school at 8 AM tomorrow).

Perfect Progressive Tenses

  • Present Perfect Progressive: Describes actions that started in the past and are still in progress (e.g., I have been walking to school for an hour).
  • Past Perfect Progressive: Describes actions that were in progress before another action in the past (e.g., I had been walking to school for an hour before it started raining).
  • Future Perfect Progressive: Describes actions that will have been in progress for a period of time before a specific time in the future (e.g., I will have been walking to school for two hours by the time I arrive).

Usage Rules for Verbs

Correct verb usage is essential for clear and effective communication. Several rules govern how verbs should be used in sentences.

Subject-Verb Agreement

Subject-verb agreement means that the verb must agree in number with its subject. If the subject is singular, the verb must be singular.

If the subject is plural, the verb must be plural.

Examples:

  • Singular: The dog barks.
  • Plural: The dogs bark.

Table 4: Subject-Verb Agreement Examples

This table provides examples of subject-verb agreement with different subjects.

Subject Verb Example
Singular Noun Singular Verb The cat sits on the mat.
Plural Noun Plural Verb The cats sit on the mat.
Singular Pronoun (I, he, she, it) Singular Verb He plays the guitar.
Plural Pronoun (we, you, they) Plural Verb They play the guitar.
Compound Subject (joined by and) Plural Verb John and Mary are friends.
Compound Subject (joined by or/nor) Verb agrees with the closest subject Neither John nor his friends are here.
Collective Noun (singular in form) Singular Verb (if acting as a unit) The team is playing well.
Collective Noun (singular in form) Plural Verb (if acting individually) The team are arguing among themselves.

Tense Consistency

Tense consistency means that the verb tenses in a sentence or paragraph should be consistent, unless there is a clear reason to change tense. Shifts in tense can confuse the reader and make the writing unclear.

Examples:

  • Incorrect: I went to the store and I will buy some milk.
  • Correct: I went to the store and I bought some milk.
  • Correct: I am going to the store and I will buy some milk.

Table 5: Tense Consistency Examples

This table provides examples of correct and incorrect tense usage in sentences.

Incorrect Correct
I went to the park, and I will have fun. I went to the park, and I had fun.
She is a doctor, but she was a teacher before. She is a doctor, but she was a teacher before. (Acceptable if the context requires both tenses.)
He eats dinner, and then he went to bed. He eats dinner, and then he goes to bed.
They are studying for the exam, and they passed it last week. They are studying for the exam, which they passed last week.

Active vs. Passive Voice

In the active voice, the subject performs the action. In the passive voice, the subject receives the action.

  • Active: The dog chased the ball.
  • Passive: The ball was chased by the dog.

While both voices are grammatically correct, the active voice is generally preferred because it is more direct and concise. The passive voice can be useful when the actor is unknown or unimportant.

Table 6: Active vs. Passive Voice Examples

This table provides examples of sentences in both active and passive voice.

Active Voice Passive Voice
The chef cooked the meal. The meal was cooked by the chef.
The students completed the assignment. The assignment was completed by the students.
The author wrote the book. The book was written by the author.
The company developed the software. The software was developed by the company.

Verb Mood (Indicative, Imperative, Subjunctive)

Verb mood indicates the attitude of the speaker or writer towards the action or state of being expressed by the verb.

  • Indicative Mood: States a fact or asks a question (e.g., She is a teacher. Is she a teacher?).
  • Imperative Mood: Gives a command or makes a request (e.g., Close the door.).
  • Subjunctive Mood: Expresses a wish, a suggestion, a necessity, or a condition that is contrary to fact (e.g., I wish I were taller. It is essential that he be on time.).

Table 7: Verb Mood Examples

This table provides examples of sentences in the indicative, imperative, and subjunctive moods.

Mood Example
Indicative He is coming to the party.
Imperative Please close the window.
Subjunctive I suggest that he be present at the meeting.
Indicative They are going to the beach.
Imperative Do your homework.
Subjunctive If I were you, I would take the job.

Common Mistakes with Verbs

Several common mistakes can occur when using verbs. Being aware of these errors can help you avoid them.

  • Subject-Verb Agreement Errors: Failing to match the verb with the subject in number (e.g., The students is studying – incorrect; The students are studying – correct).
  • Tense Consistency Errors: Shifting tenses unnecessarily (e.g., I went to the store, and I will buy some milk – incorrect; I went to the store, and I bought some milk – correct).
  • Incorrect Verb Forms: Using the wrong form of the verb (e.g., I have went to the store – incorrect; I have gone to the store – correct).
  • Misuse of Active and Passive Voice: Using the passive voice when the active voice would be more direct (e.g., The report was written by me – less direct; I wrote the report – more direct).
  • Errors in Verb Mood: Using the wrong mood, especially with the subjunctive (e.g., I wish I was taller – incorrect; I wish I were taller – correct).

Advanced Topics in Verb Usage

For advanced learners, understanding more complex aspects of verb usage can further enhance their writing and communication skills.

Conditional Sentences

Conditional sentences express a condition and its result. There are four main types of conditional sentences:

  • Zero Conditional: Expresses a general truth (e.g., If you heat water to 100 degrees Celsius, it boils).
  • First Conditional: Expresses a possible condition and its probable result (e.g., If it rains, I will stay home).
  • Second Conditional: Expresses an unlikely or hypothetical condition and its probable result (e.g., If I won the lottery, I would travel the world).
  • Third Conditional: Expresses a past condition that did not happen and its hypothetical result (e.g., If I had studied harder, I would have passed the exam).

Subjunctive Mood (Advanced)

The subjunctive mood is used to express wishes, suggestions, commands, or hypothetical situations. It often appears in “that” clauses after verbs such as suggest, recommend, demand, and insist.

Examples:

  • I suggest that he be present at the meeting. (Subjunctive)
  • It is essential that she arrive on time. (Subjunctive)
  • If I were you, I would accept the offer. (Subjunctive)

Note that the subjunctive mood often uses the base form of the verb (without the “s” for third-person singular) and the verb “were” instead of “was” in hypothetical situations.

Idiomatic Expressions with Verbs

Idiomatic expressions are phrases whose meaning cannot be understood from the literal meanings of the individual words. Many idiomatic expressions involve verbs and require specific prepositions or adverbs.

Examples:

  • Look forward to (expect with pleasure): I look forward to seeing you.
  • Get along with (have a good relationship): They get along with each other very well.
  • Take after (resemble): She takes after her mother.
  • Put up with (tolerate): I can’t put up with his behavior any longer.

Mastering idiomatic expressions can enhance your fluency and make your writing more natural. Pay attention to the specific prepositions and adverbs that accompany these verbs.

Frequently Asked Questions

What is the difference between a linking verb and a helping verb?

A linking verb connects the subject to a noun or adjective that describes the subject (e.g., is, are, seems). A helping verb (auxiliary verb) is used with a main verb to form a verb phrase and express tense, mood, or voice (e.g., am, have, will).

How can I improve my subject-verb agreement skills?

Pay close attention to the subject of the sentence and identify whether it is singular or plural. Be especially careful with compound subjects, collective nouns, and indefinite pronouns.

Practice identifying the subject and verb in various sentences.

When should I use the active voice instead of the passive voice?

Generally, the active voice is preferred because it is more direct and concise. Use the passive voice when the actor is unknown or unimportant, or when you want to emphasize the action rather than the actor.

What is the subjunctive mood, and when should I use it?

The subjunctive mood is used to express wishes, suggestions, commands, or hypothetical situations. It often appears in “that” clauses after verbs such as suggest, recommend, demand, and insist. It is also used in “if” clauses expressing conditions contrary to fact.

How can I avoid tense consistency errors in my writing?

Be mindful of the time frame you are writing about and use verb tenses consistently. Avoid unnecessary shifts in tense.

If you need to change tense, make sure there is a clear reason for doing so.

Conclusion

Mastering verb usage is essential for success on the SAT Writing and Language section and for effective communication in general. By understanding the different types of verbs, verb tenses, usage rules, and common mistakes, you can improve your writing skills and avoid errors.

Practice identifying and correcting verb errors in various contexts to reinforce your knowledge. With diligent study and practice, you can confidently tackle verb-related questions on the SAT and enhance your overall writing abilities.
