Irregular Verbs
Verbs are subdivided into two groups, regular verbs and irregular verbs, on the basis of how their past tense and past participles are formed. Most verbs are regular verbs. Regular verbs are those whose past tense and past participles are formed by adding a -d or an -ed to the end of the verb, for example, roll and rolled. Sometimes the last consonant must be doubled before adding the -ed ending, as in, plan and planned. So far, so good.
However, English being the contrary language that it is, there are also nearly 300 irregular verbs and there is no formula to predict how such a verb will form its past tense and past participle states. Some do not change at all, others change completely, while others change letters in the middle. It's no wonder the student of English sometimes gets confused. To make things a little easier, here is a table of all the irregular verbs.
