What Are Irregular Verbs?

There is an old Japanese saying that goes something like this: “A nail that sticks out gets hammered down.” Sure, there are advantages to being normal or regular. Regular verbs in English are relatively easy to form in different tenses. Being irregular isn’t so bad, though. In fact, irregular verbs show just how diverse the English language is. The tricky part is knowing which verbs are irregular and how to properly use them in writing.

What are Irregular Verbs?

What’s an irregular verb? Irregular verbs are known as strong verbs because their past participle and past simple spelling patterns are exactly the same. Where regular verbs typically include a -d or -ed when in past participle or past simple forms, verbs that are irregular do not.

How to Identify Irregular Verbs

If there is a simple way to conjugate regular verbs, then there must also be a distinctive pattern in order to determine the formation of irregular verbs, right? Not so with English. Irregular verbs are just that: irregular, unpredictable. In order to use an irregular verb correctly, you just have to learn all of its different forms by heart. As was stated above, you can tell if a verb is irregular by putting it in its simple past and past participle forms; if it doesn’t end with –d or –ed, then it is an irregular verb.

Here are some irregular verb examples:

– The boys dug into the dirt to look for worms.

– They brought me a caterpillar they had found.

Dug, brought and found are irregular because the simple past tense and past participle are not formed by placing –d or –ed onto the base verb (dig, bring and find). It is also important to note that some irregular verbs can seem regular when looking at the past tense.

– The bubble swelled to a size I’d never before seen.

– After eating a Thanksgiving feast, my stomach is swollen to uncomfortable proportions.

In the first irregular verb example, swelled meets the requirement of ending in –ed in the past tense. It is when we look at a past participle that we see swell becomes swollen, which is irregular. So swell is an irregular verb.

Mistakes Writers Make With Irregular Verbs

There are two common mistakes that writers make with irregular verbs.

1. Adding an –ed to the end of an irregular verb. This is an easy mistake for non-native English speakers to make.

– Incorrect: Sam drived to work in the 4Runner because the Camry didn’t start. 

– Correct: Sam drove to work in the 4Runner because the Camry didn’t start. 

2. Mixing up the simple past and past participle. The simple past tense of an irregular verb will not necessarily be the same as its past participle, as noted in the examples with swelled and swollen. Here is another example with the simple past and past participle of drink (drank and drunk):

– Incorrect: I drunk cranberry juice because it’s healthy and I like the way it tastes. 

– Correct: I drank cranberry juice because it’s healthy and I like the way it tastes. 
– Incorrect: I have to run to the bathroom; I may have drank too much cranberry juice. 

– Correct: I have to run to the bathroom; I may have drunk too much cranberry juice.
