What are Irregular Verbs?
Irregular verbs are verbs in English that do not follow the standard pattern of adding “-ed” or “-d” to the base form to create the past tense and past participle. Instead, they have unique and often unpredictable forms that must be memorized.
These verbs represent a significant part of the English language and are essential for accurate and fluent communication. Understanding and mastering irregular verbs is crucial for both speaking and writing effectively.
Regular verbs, in contrast, are predictable. For example, the regular verb “walk” becomes “walked” in the past tense and past participle.
Irregular verbs, however, might change their vowel sounds (e.g., “sing” becomes “sang”), change completely (e.g., “go” becomes “went”), or remain the same (e.g., “cut” remains “cut”). This irregularity is what makes them challenging for learners.
The irregularity stems from the historical development of the English language. Many irregular verbs are remnants from Old English, where verb conjugations were more complex.
As the language evolved, many verbs were regularized, but a core group of common verbs retained their irregular forms.
Structural Breakdown of Irregular Verbs
The structure of irregular verbs can be analyzed based on how the verb changes from its base form (present tense) to its past tense and past participle forms. These changes can involve alterations in vowel sounds, consonant sounds, or a complete change in the word itself.
Analyzing these structural changes can help in memorization and understanding.
Common Structural Patterns
While irregular verbs, by definition, don’t follow a strict rule, some patterns can be observed:
- Vowel Change: Many irregular verbs change their vowel sound in the past tense and past participle. For example, “swim” becomes “swam” and “swum.”
- Vowel Change + ‘n’: Some verbs change their vowel and add an “n” or “en” to form the past participle. For example, “break” becomes “broke” and “broken.”
- No Change: Some irregular verbs have the same form in the present, past tense, and past participle. For example, “cut,” “hit,” and “cost” remain the same.
- Complete Change: A few verbs undergo a complete transformation in the past tense. For example, “go” becomes “went.”
Understanding these patterns, however loose they may be, can aid in memorizing the different forms of irregular verbs. It’s important to note that these are tendencies rather than strict rules.
Categories of Irregular Verbs
Irregular verbs can be categorized based on how they change from their base form to the past tense and past participle. Here’s a breakdown of the main categories:
1. Verbs with the Same Base, Past Tense, and Past Participle
These verbs are the easiest to remember because their form doesn’t change. Examples include “cut,” “hit,” “let,” and “put.”
2. Verbs with the Same Past Tense and Past Participle
In this category, the past tense and past participle forms are identical, but different from the base form. Examples include “bring” (brought, brought), “feel” (felt, felt), and “think” (thought, thought).
3. Verbs with Different Base, Past Tense, and Past Participle Forms
These are often the most challenging irregular verbs because all three forms are distinct. Examples include “sing” (sang, sung), “go” (went, gone), and “write” (wrote, written).
4. Verbs with Vowel Changes Only
These verbs typically involve a change in the vowel sound between the base form and the past tense, with the past participle often adding an “-en” ending. Examples include “begin” (began, begun), “drink” (drank, drunk), and “speak” (spoke, spoken).
Examples of Irregular Verbs

Usage Rules for Irregular Verbs
Using irregular verbs correctly requires understanding their different forms and how they function in various tenses and grammatical structures. Here are some key usage rules:
1. Past Simple Tense
Use the past tense form of the irregular verb to describe completed actions in the past. For example: “I went to the store yesterday.”
2. Present Perfect Tense
Use the past participle form with the auxiliary verb “have” or “has” to describe actions that started in the past and continue to the present or have a result that affects the present. For example: “I have eaten dinner.”
3. Past Perfect Tense
Use the past participle form with the auxiliary verb “had” to describe actions that were completed before another action in the past. For example: “I had finished my homework before I went out.”
4. Passive Voice
Use the past participle form after a form of the verb “be” (is, are, was, were, been, being) to form the passive voice. For example: “The book was written by a famous author.”
5. Gerunds and Infinitives
Irregular verbs can also appear in gerunds (verb + -ing) and infinitives (to + verb), but their irregular forms are not used in these cases. For example: “Going to the beach is fun.” “I want to go to the party.”
Exceptions and Special Cases
Some irregular verbs have regional variations or alternative forms. For example, the past participle of “get” can be “got” or “gotten,” with “gotten” being more common in American English.
Common Mistakes with Irregular Verbs
One of the most frequent errors in English grammar involves the incorrect use of irregular verb forms. Here are some common mistakes and how to correct them:
1. Using the Base Form Instead of the Past Tense
- Incorrect: I go to the store yesterday.
- Correct: I went to the store yesterday.
2. Using the Base Form Instead of the Past Participle
- Incorrect: I have see that movie.
- Correct: I have seen that movie.
3. Using the Past Tense Form Instead of the Past Participle

Advanced Topics: Nuances and Exceptions
Delving deeper into irregular verbs reveals further complexities and nuances. This section explores some advanced topics for learners seeking a more comprehensive understanding.
1. Archaic Forms and Regional Variations
Some irregular verbs have archaic forms that are rarely used in modern English. For example, the past participle of “show” can be “shown” or “shewn,” with “shewn” being an older form.
Additionally, regional variations exist, such as the use of “gotten” in American English and “got” in British English as the past participle of “get.”
2. Verbs with Multiple Irregular Forms
A few verbs have multiple acceptable irregular forms. For example, the past participle of “dream” can be “dreamed” or “dreamt.” The choice often depends on regional preference or stylistic considerations.
3. Irregular Verbs in Idiomatic Expressions
Irregular verbs frequently appear in idiomatic expressions, where their meaning may be different from their literal sense. Understanding these expressions requires familiarity with both the verb and the idiom.
For example, “to get over something” means to recover from an illness or emotional setback.
4. The Subjunctive Mood
While less common in modern English, the subjunctive mood sometimes utilizes the base form of verbs, even when a past tense might be expected. This is often seen in formal or literary contexts, particularly in “if” clauses expressing wishes or hypothetical situations. For example, “If I were you, I would take the job.” (Here, ‘were’ is the subjunctive form of ‘be’).
Frequently Asked Questions
This section addresses common questions about irregular verbs to further clarify their usage and address potential points of confusion.
- Why are some verbs irregular?
Irregular verbs are remnants from older forms of English. Over time, many verbs were regularized, but some common verbs retained their original irregular forms due to frequent use and historical linguistic patterns.
- Is there a way to predict which verbs are irregular?
Unfortunately, there is no foolproof way to predict which verbs are irregular. However, many irregular verbs share common patterns of vowel changes or other alterations, which can aid in memorization. The best approach is to study lists of irregular verbs and practice using them in context.
- How can I best memorize irregular verbs?
Effective memorization techniques include using flashcards, creating mnemonic devices, practicing verb conjugations, and reading and listening to English to see and hear the verbs used in context. Consistent practice and exposure are key.
- Are irregular verbs more common in certain tenses?
Irregular verbs are used across all tenses, but they are particularly important in the past simple, present perfect, and past perfect tenses, where their irregular forms are essential for correct grammar.
- What is the difference between “lie” and “lay”?
This is a common source of confusion. “Lie” (to recline) is an irregular verb: lie, lay, lain. “Lay” (to place something) is a transitive verb (it takes an object) and its forms are: lay, laid, laid. For example: “I lie down to rest” (present), “I lay down yesterday” (past), “I have lain down” (past participle). “I lay the book on the table” (present), “I laid the book on the table” (past), “I have laid the book on the table” (past participle).
- Why do some verbs have two past participle forms?
Some verbs have two past participle forms due to historical changes in the language or regional variations. For example, “get” has “got” and “gotten,” with “gotten” being more common in American English. Both forms are generally acceptable, but it’s helpful to be aware of the differences.
- How do I know when to use the past tense vs. the past participle?
The past tense is used for simple past actions, while the past participle is used with auxiliary verbs like “have,” “has,” or “had” in perfect tenses, or with forms of “be” in the passive voice. Understanding the function of each tense is crucial for using the correct form of the verb.
- Are there any resources that can help me practice irregular verbs?
Yes, numerous online resources, textbooks, and apps offer practice exercises, quizzes, and interactive tools for learning irregular verbs. Look for resources that provide clear explanations, ample examples, and opportunities for personalized practice.
Conclusion
Mastering irregular verbs is a crucial step towards achieving fluency and accuracy in English. While they may seem daunting at first, with consistent study, practice, and attention to detail, you can confidently navigate their complexities.
