What Are Irregular Verbs?

An irregular verb is one that does not form its simple past tense or its past participle by adding "-ed" or "-d" to the base form.

Irregular verbs contrast with regular verbs, which form the simple past tense and past participle by adding "-ed" or "-d."

Let's compare an irregular verb to a regular verb:

Irregular Verb	Simple Past Test	Past Participle
arise	arose	arisen
Regular Verb	Simple Past Test	Past Participle
jump	jumped	has jumped

Remember that the simple past tense describes a completed activity that happened in the past. For example:

• Alan forgot the balloon.
• Sarah froze the fish.

The past participle is the form that can be used with "have" to form a specific verb tense or as an adjective. For example:

• Oops, I have forgotten the balloons.
• Buy frozen fish.

Why Irregular Verbs Are Important

Somewhat counter-intuitively, the most common verbs in English are irregular. So, if you're learning or teaching English, you must embrace them. There's no real trick to learning how to use irregular verbs. You just have to learn them. The truth is that you won't master English without studying them.

Good luck!
