Introduction

In the previous unit, we worked with the Present Perfect using regular verbs. You learned that regular verbs simply add -ed to form the past participle. However, English is not always regular and predictable. Many common verbs do not follow this pattern, and their past participle forms are irregular.

In this lesson, we will focus on the most essential irregular past participles. These verbs are extremely common in everyday English, and mastering them will allow you to form perfect tenses correctly and confidently.

By the end of this unit, you will be able to recognize and use essential irregular past participles correctly. You will understand how they differ from regular verbs and how to use them accurately in the Present Perfect and other perfect tenses.

1. Why Irregular Past Participles Matter

Perfect tenses require the past participle form.
Whenever we form the Present Perfect, Past Perfect, or Future Perfect, we need the past participle. For regular verbs, this is easy. But for irregular verbs, the form changes and must be memorized.

For example, the verb “go” does not become “goed.” Instead, the correct past participle is “gone.” So we say, “I have gone to the supermarket,” not “I have goed.”

These irregular forms are essential because many of them are among the most frequently used verbs in English: be, go, do, see, take, make, come, give, find, and others.

2. Common Irregular Verbs and Their Past Participles

Let us now look at a selection of the most important irregular verbs at A2 level. You do not need to memorize hundreds of verbs. Focus on the most common ones first.

As you can see, some verbs change completely, such as go → gone. Others remain the same in the past simple and past participle, such as made or found. Each verb must be learned individually.

3. Using Irregular Participles in the Present Perfect

Now let us see how these verbs work inside sentences.

“I have seen that movie.” The verb “see” becomes “seen.”

“She has taken the bus.” The verb “take” becomes “taken.”

“We have done our homework.” The verb “do” becomes “done.”

Notice that the auxiliary verb have or has remains the same. Only the past participle changes.

Do not confuse Past Simple with Past Participle.
A very common mistake is saying: “I have went” or “She has saw.” These are incorrect because “went” and “saw” are Past Simple forms. In the Present Perfect, we must use “gone” and “seen.”

4. Patterns and Observations

Although irregular verbs must be memorized, you may notice some small patterns. Many past participles end in -en, such as taken, given, seen, been. Others remain identical to the Past Simple, such as made, found, had.

However, it is important not to rely only on patterns. The safest approach at this level is gradual exposure and repetition. The more you read and listen to English, the more natural these forms will become.
