Regular verbs form their past tense and past participle by adding -ed to the base form.
Here are some examples:
* Base Form | Past Tense | Past Participle
* walk | walked | walked
* talk | talked | talked
* play | played | played
* jump | jumped | jumped
* cook | cooked | cooked
Important Note: There are also irregular verbs that do not follow this rule. They have unique forms for past tense and past participle (e.g., go - went - gone, see - saw - seen).
