1. Regular Verbs: These verbs form their past tense by adding -ed to the base form.
* Examples: walk - walked, jump - jumped, play - played
2. Irregular Verbs: These verbs have unique past tense forms that don't follow the -ed rule.
* Examples: go - went, see - saw, eat - ate, have - had
It's important to remember that some verbs can be both regular and irregular depending on their meaning. For example, "set" is irregular (set - set) when it refers to placing something, but "set" can also be regular (set - setted) when it refers to making something firm or fixed.
