The past tense of the verb "choose" is "chose," while the past participle is also "chosen."
When we talk about an action that happened in the past, we use the past tense. For example, "He chose the red dress for the party." Here, "chose" is the past tense of "choose."
On the other hand, the past participle is used in perfect tenses and passive voice constructions. For example, "The winner has been chosen." In this sentence, "chosen" is the past participle of "choose."
It's important to remember that irregular verbs like "choose" don't follow the regular rules for forming past tense and past participle. Instead, they have their unique forms, like "chose" and "chosen" in the case of "choose."
So, next time you want to talk about a past action or use perfect tenses, remember the past tense "chose" and the past participle "chosen" for the verb "choose."
