The present perfect tense of the verb ‘throw’ is ‘have thrown’ or ‘has thrown’.
This tense is formed using the auxiliary verb ‘have’ or ‘has’ followed by the past participle of the main verb. In this case, the past participle of ‘throw’ is ‘thrown’. Therefore, to indicate that someone has thrown something at some point in the past with relevance to the present, we use:
- Have thrown: for plural subjects and the pronouns ‘I’, ‘you’, ‘we’, and ‘they’
- Has thrown: for singular subjects and the pronouns ‘he’, ‘she’, and ‘it’
For example:
- I have thrown the ball.
- She has thrown the paper into the basket.
Using the present perfect tense helps to link past actions to the present, making it clear that the action of throwing is relevant now.
