English regular verbs change their form very little (unlike irregular verbs). The past tense and past participle of regular verbs end in -ed, for example:
work, worked, worked
But you should note the following points:
1. Some verbs can be both regular and irregular, for example:
learn, learned, learned
learn, learnt, learnt
2. A few verbs have one meaning when regular and a different meaning when irregular, for example the verb to lie:
|regular||lie||lied||lied||to say untrue things||Why do you lie about everything? You lied to me yesterday. And you have just lied to me again.|
|irregular||lie||lay||lain||to be down flat||Normally I lie on the floor for my back exercises. But yesterday I lay on the bed. I have never lain on the sofa.|
3. The present tense of some regular verbs is the same as the past tense of some irregular verbs, for example the verbs to found and to find:
|regular||found||founded||founded||to start or establish an organization such as a school or business||Did Steve Jobs found Apple?
Reed's School was founded by Andrew Reed.
|irregular||find||found||found||to discover something||Where did you find your keys? / I found them in the car.|
