What Are Irregular Verbs? Definition, Rules, Examples and Exercises

Have you ever noticed that in English, some verbs don’t follow the usual rules? For example, we say “walk - walked,” but not “go - goed”; instead, we say “go - went.” These verbs are called irregular verbs, and they do not follow the regular “-ed” pattern for the past tense. In this guide, you will learn about irregular verbs, their rules, examples, and the difference between regular and irregular verbs.

What are Irregular Verbs?

An irregular verb is a verb that does not follow the standard rules of grammar when forming its past tense and past participle. While regular verbs typically form these tenses by adding “-ed” to the base form, irregular verbs do not follow this pattern. For example, “go” becomes “went” and “gone,” while “eat” changes to “ate” and “eaten,” rather than following a predictable structure. Therefore, it is important to learn and memorise these unique forms, as they are commonly used in everyday communication, including speaking, writing, and academic work.

Rules for Conjugating Irregular Verbs

Learning to conjugate irregular verbs may seem challenging at first, but it is not as difficult as it appears. With a clear understanding of their patterns, they can be learned easily with practice. Irregular verbs do not follow a single rule when forming their simple past and past participle forms. However, they can be grouped into three main categories based on how they change.

• Group 1: Verbs that remain the same in all three forms (base, past, and past participle), such as cut → cut → cut.

• Group 2: Verbs that have the same form in the simple past and past participle, though some may also have alternate spellings, such as buy → bought → bought.

• Group 3: Verbs that have different forms for the base verb, simple past, and past participle, such as go → went → gone.

By recognising these patterns and grouping similar verbs together, you can understand and remember irregular verbs more effectively. Regular practice is key to mastering their usage in everyday communication.

 

Examples of Irregular Verbs

Irregular verbs do not follow a fixed pattern when they change from their base form to the past and past participle forms. To make them easier to understand and learn, they can be grouped based on how their forms change. The table below shows the forms of irregular verbs grouped based on these patterns.

Group 1: Irregular Verbs with the Same Spelling in All Forms 

Here is a group of irregular verbs that do not change their spelling at all.

 

Group 2: Irregular Verbs with the Same Simple Past and Past Participle Form 

These verbs have the same second and third forms, that is, the simple past and past participle form.

 

Group 3: Irregular Verbs with Different Spelling in All Forms

Here are the verbs that change in all three forms. 

 

An Alternative Method to Learn Irregular Verbs and Their Conjugation

Another effective way to learn irregular verbs is to group them by how their spellings change from the base form to the simple past and past participle. This method makes it easier to identify patterns and remember them. Take a look at the categories below:

Difference Between Regular and Irregular Verbs

Regular and irregular verbs differ in how they form their past tense and past participle. Regular verbs follow a predictable pattern by adding “-ed” or “-d” to the base form, such as talk → talked → talked. In contrast, irregular verbs do not follow this rule and change in unique ways, such as go → went → gone or eat → ate → eaten. Because of these variations, irregular verbs need to be learned and memorised, while regular verbs are easier to use due to their consistent structure.
