However, you can use regular and irregular verbs together in a sentence. For example:
* She walked quickly to the store and bought some milk. (walked - regular, bought - irregular)
* I see the bird flying high above the trees. (see - irregular, flying - irregular)
The key is that each verb is conjugated correctly based on its own rules.
* Regular verbs follow a consistent pattern for forming their past tense and past participle (adding -ed or -d).
* Irregular verbs have unpredictable forms that need to be memorized.
So, while you can't combine them in a strange way, you can use them together in sentences where they each play their own role.
