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. Some verbs have one meaning when regular and a different meaning when irregular, for example the verb to hang:
|regular||hang||hanged||hanged||to kill or die, by dropping with a rope around the neck||When will they hang the murderer? / They have hanged him already. He was hanged at dawn.|
|irregular||hang||hung||hung||to fix something (for example, a picture) at the top so that the lower part is free||Where will you hang the new picture? / I've hung it already. I hung it in the lobby.|
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.|
