Definition of Helping Verbs
Helping verbs, also known as auxiliary verbs, are verbs that precede the main verb in a sentence. Their primary function is to provide grammatical information about tense, mood, voice, aspect, and emphasis.
They “help” the main verb by adding these layers of meaning. Without helping verbs, it would be difficult to express complex ideas about time, possibility, obligation, or permission.
Helping verbs are classified into two main categories: primary auxiliary verbs and modal auxiliary verbs. Primary auxiliaries include forms of be, do, and have. Modal auxiliaries, on the other hand, express possibility, necessity, permission, ability, or obligation. These include verbs like can, could, may, might, must, shall, should, will, and would.
The context in which a helping verb is used is crucial for understanding its specific function. For instance, the verb “be” can indicate continuous tense (He is running) or passive voice (The book was written). Similarly, “have” is used to form perfect tenses (They have finished). Modal verbs always add a layer of meaning related to possibility, obligation, or ability, as in “You should study” or “I can swim.” Recognizing these functions is key to mastering English grammar.
Structural Breakdown
The structure of a sentence with a helping verb typically follows this pattern: Subject + Helping Verb(s) + Main Verb. It’s important to note that a sentence can contain one or more helping verbs, especially when expressing complex tenses or moods. For example, in the sentence “She might have been studying,” might, have, and been are all helping verbs contributing to the overall meaning of the sentence.
The helping verb always precedes the main verb. The main verb is the action word that denotes the primary activity within the sentence.
The helping verb modifies the meaning of that action. The main verb often appears in a specific form depending on the preceding helping verb.
For instance, after forms of “be” in continuous tenses, the main verb takes the -ing form (present participle), as in “They are playing.” After “have” in perfect tenses, the main verb typically takes the past participle form, as in “We have eaten.”
Understanding the structural roles of helping verbs is fundamental to constructing grammatically sound sentences. By correctly placing helping verbs before the main verb and ensuring that the main verb is in the appropriate form, you can effectively convey the intended meaning and avoid common grammatical errors.
The following table illustrates some basic structures:
| Structure | Example Sentence | Explanation |
|---|---|---|
| Subject + is/are/am + Verb-ing | They are playing football. | Present continuous tense. |
| Subject + have/has + Verb (past participle) | She has finished her work. | Present perfect tense. |
| Subject + will + Verb (base form) | He will travel to Europe. | Future simple tense. |
| Subject + can/could/may/might/must + Verb (base form) | You should study hard. | Modal verb indicating obligation. |
| Subject + had + Verb (past participle) | I had eaten before he arrived. | Past perfect tense. |
Types and Categories of Helping Verbs
Helping verbs are broadly classified into two main categories: primary auxiliary verbs and modal auxiliary verbs. Each category has its unique functions and contributes differently to the meaning of a sentence.
Primary Auxiliary Verbs
The primary auxiliary verbs are forms of be, do, and have. These verbs can function as both main verbs and helping verbs, depending on the context. When they act as helping verbs, they primarily assist in forming different tenses, voices (active and passive), and questions.
Forms of be (am, is, are, was, were, being, been) are used to create continuous tenses and the passive voice. For example, “She is reading” (present continuous) and “The house was built” (passive voice). Forms of do (do, does, did) are used to form questions and negative statements in the simple present and simple past tenses. For example, “Do you like coffee?” and “He did not go.” Forms of have (have, has, had) are used to form perfect tenses, indicating completed actions. For example, “They have finished” (present perfect) and “We had left” (past perfect).
Here’s a table summarizing the primary auxiliary verbs and their main functions:
| Primary Auxiliary Verb | Forms | Function | Example |
|---|---|---|---|
| Be | am, is, are, was, were, being, been | Continuous tenses, passive voice | She is singing. The letter was written. |
| Do | do, does, did | Questions, negative statements (simple present/past) | Do you understand? He did not agree. |
| Have | have, has, had | Perfect tenses | They have arrived. We had finished. |
Modal Auxiliary Verbs
Modal auxiliary verbs, often referred to simply as modal verbs, express possibility, necessity, permission, ability, obligation, advice, or probability. They always accompany a main verb and add a specific nuance to its meaning. The most common modal verbs are can, could, may, might, must, shall, should, will, and would.
Each modal verb conveys a distinct meaning. Can and could express ability or possibility (I can swim, It could rain). May and might express permission or possibility (You may leave, It might snow). Must expresses necessity or strong obligation (You must study). Shall and will are used to form the future tense (I shall go, He will arrive). Should expresses advice or obligation (You should exercise). Would expresses willingness, polite requests, or hypothetical situations (I would help, Would you mind?).
Modal verbs have several unique characteristics. They do not change form based on the subject (e.g., he can, not he cans). They are always followed by the base form of the main verb (e.g., He can swim, not He can swimming). They are used to form questions by inverting the subject and the modal verb (e.g., Can you help?). They form negative statements by adding “not” after the modal verb (e.g., You cannot go).
Here’s a table summarizing the modal auxiliary verbs and their common meanings:
| Modal Auxiliary Verb | Meaning | Example |
|---|---|---|
| Can | Ability, possibility | I can speak Spanish. It can be difficult. |
| Could | Ability (past), possibility, polite request | She could sing well. It could rain. Could you help me? |
| May | Permission, possibility | You may enter. It may be true. |
| Might | Possibility | It might snow tonight. |
| Must | Necessity, obligation | You must pay attention. |
| Shall | Future (formal), suggestion | I shall return. Shall we dance? |
| Should | Advice, obligation | You should see a doctor. |
| Will | Future, willingness | I will go. I will help you. |
| Would | Polite request, hypothetical | Would you like tea? I would travel if I could. |

Usage Rules for Helping Verbs
Proper usage of helping verbs requires adherence to specific grammatical rules. These rules govern subject-verb agreement, tense consistency, forming negative sentences, and asking questions.
Subject-Verb Agreement
Helping verbs must agree with the subject in number (singular or plural). For example, “He is going” (singular) and “They are going” (plural). With the verb “have,” the singular form is “has” (e.g., “She has finished”), and the plural form is “have” (e.g., “They have finished”).
Here’s a table illustrating subject-verb agreement with primary auxiliary verbs:
| Subject | Helping Verb | Example |
|---|---|---|
| I | am, have | I am studying. I have finished. |
| He/She/It | is, has | He is working. She has arrived. |
| You/We/They | are, have | You are learning. We have eaten. |
Tense Consistency
Maintain consistency in tense throughout a sentence or paragraph. If you start in the past tense, generally continue in the past tense. For example, “He was tired, so he went to bed” (both verbs in the past tense). Avoid unnecessary shifts in tense that can confuse the reader.
Consider the following examples:
- Correct: She had finished her work and then went to the store. (Both past perfect and past simple)
- Incorrect: She had finished her work and then goes to the store. (Inconsistent tense)
Forming Negative Sentences
To form negative sentences with helping verbs, add “not” after the helping verb. Contractions like “isn’t,” “aren’t,” “wasn’t,” “weren’t,” “haven’t,” “hasn’t,” “hadn’t,” “don’t,” “doesn’t,” “didn’t,” and modal verb contractions (e.g., “can’t,” “won’t,” “shouldn’t”) are commonly used.
Examples:
- He is not going. (He isn’t going.)
- They have not arrived. (They haven’t arrived.)
- She did not call. (She didn’t call.)
- You should not do that. (You shouldn’t do that.)
Forming Questions
To form questions with helping verbs, invert the subject and the helping verb. For example, “Is she coming?” (instead of “She is coming.”) and “Have they finished?” (instead of “They have finished.”).
When using “do,” “does,” or “did” to form questions, remember to use the base form of the main verb (e.g., “Did you go?” not “Did you went?”).
Examples:
- Is he here?
- Are they ready?
- Have you eaten?
- Did she call?
- Can you help me?
- Will they arrive soon?
Common Mistakes with Helping Verbs
Several common errors can occur when using helping verbs. Recognizing these mistakes will help you avoid them and improve your grammar.
| Incorrect | Correct | Explanation |
|---|---|---|
| He have finished. | He has finished. | Subject-verb agreement: “He” requires “has.” |
| She don’t like coffee. | She doesn’t like coffee. | Subject-verb agreement: “She” requires “doesn’t.” |
| I be going to the store. | I am going to the store. | Correct form of “be” for “I” is “am.” |
| Did he went to the party? | Did he go to the party? | Use the base form of the verb after “did.” |
| I can to swim. | I can swim. | Modal verbs are followed by the base form of the verb without “to.” |
| They must studied hard. | They must study hard. | Modal verbs are followed by the base form of the verb. |
| She have been working here for five years. | She has been working here for five years. | “She” requires “has” in the present perfect continuous tense. |
| We was watching TV last night. | We were watching TV last night. | “We” requires “were” in the past continuous tense. |
| He is liking pizza. | He likes pizza. | “Like” is a stative verb and not normally used in continuous tenses. |
| I am agree with you. | I agree with you. | “Agree” is a stative verb and not normally used in continuous tenses. |

Advanced Topics
For advanced learners, understanding these more complex aspects of helping verbs can further refine your English grammar skills.
Emphatic Do
The auxiliary verb do can be used for emphasis in affirmative sentences. This is often used to express surprise, contradiction, or strong affirmation.
Examples:
- I do like coffee! (Emphasis on liking coffee)
- He does care about you. (Emphasis on caring)
- They did finish the project. (Emphasis on completing the project)
Auxiliary Inversion
Auxiliary inversion involves inverting the helping verb and the subject, primarily used in questions or after certain adverbs (e.g., never, rarely, seldom). This creates a more formal or emphatic tone.
Examples:
- Have you finished?
- Rarely do they visit.
- Never had I seen such a thing.
Dummy Auxiliary
In some cases, the auxiliary verb ‘do’ is referred to as a dummy auxiliary. This is because it is grammatically required to form a question or a negative statement, but it doesn’t add any meaning to the verb.
Examples:
- Do you like chocolate?
- I don’t like chocolate
Frequently Asked Questions
Here are some frequently asked questions about helping verbs:
- What is the difference between a helping verb and a main verb?
A helping verb assists the main verb by adding information about tense, mood, voice, or aspect. The main verb expresses the primary action or state of being in the sentence. For example, in “She is singing,” is is the helping verb and singing is the main verb.
- Can a verb be both a helping verb and a main verb?
Yes, the verbs be, do, and have can function as both helping verbs and main verbs. When they are the only verb in the sentence, they are main verbs (e.g., “I am happy.”). When they precede another verb, they are helping verbs (e.g., “I am studying”).
- How do I form negative sentences with modal verbs?
To form negative sentences with modal verbs, add “not” after the modal verb. Contractions are commonly used (e.g., “cannot” becomes “can’t,” “will not” becomes “won’t,” “should not” becomes “shouldn’t”). For example, “You should not go” or “You shouldn’t go.”
- What is the correct order of helping verbs in a sentence?
When multiple helping verbs are used, the typical order is modal verb (if present), followed by a form of “have,” followed by a form of “be.” For example, “She might have been studying.”
- How do I know which modal verb to use?
The choice of modal verb depends on the intended meaning. Can and could indicate ability or possibility. May and might indicate possibility or permission. Must indicates necessity or obligation. Should indicates advice or obligation. Will indicates future intention. Would indicates a polite request or hypothetical situation. Consider the context and the specific nuance you want to convey.
- Are there any irregular modal verbs?
Modal verbs are generally considered irregular because they do not follow the typical conjugation patterns of other verbs. They do not add “-s” in the third-person singular (e.g. “he can” not “he cans”), and they do not have infinitive or participle forms.
- When should I use ‘shall’ instead of ‘will’?
‘Shall’ is traditionally used with ‘I’ and ‘we’ to form the future tense in formal English. However, ‘will’ is now commonly used with all subjects in modern English. ‘Shall’ is also used to make suggestions or offers, such as “Shall we go?”.
- How do I use helping verbs in passive voice sentences?
In passive voice sentences, a form of the helping verb “be” is always used, along with the past participle of the main verb. The subject of the sentence receives the action, rather than performing it. For example, “The book was written by her.”
