2.2.2.4   Regular verbs and Irregular verbs

            

                         Main verbs can also be classified into regular verbs and irregular verbs.

         

                         The only difference between regular and irregular verbs is that they have different endings for
                         their past tense and past participle forms. For regular verbs, the past tense ending and past
                         participle ending is always the same: -ed. For irregular verbs, the past tense ending and the past
                         participle ending is variable, so it is necessary to learn them by heart.

 

                2.2.2.4.1   Regular verb examples:
 

• look, looked, looked

• work, worked, worked

• jump, jumped, jumped

                    

                2.2.2.4.2  Irregular verb examples:

​

• go, went, gone

• sleep, slept, slept

• cut, cut, cut

 

    * When writing the main verbs in a sentence, many of my students often have the be form and the do form
       mixed up, or write both into a sentence. Some of them would write a sentence like: “He is sit on the chair.”
       Perhaps this is a common mistake among non-native speakers when learning English.
