In English, regular verbs consist of three main parts: the root form (present), the (simple) past, and the past participle. Regular verbs have an -ed ending added to the root verb for both the simple past and past participle. Irregular verbs do not follow this pattern, and instead take on an alternative pattern.
Irregular verbs are an important feature of English. We use irregular verbs a lot when speaking, less when writing. Of course, the most famous English verb of all, the verb "to be", is irregular.
