 have a look at the present perfect tense. The form for the present perfect tense is, again, our subjects here, our auxiliary verb or our helping verb, in this case it's have. For subjects i, u, we, and they, we leave the auxiliary verb as have. For he, she, and it, our auxiliary verb needs to be conjugated or changed into has. Following these helping verbs, we have our main verb in the past participle form. Here we have the verb to play. To play is a regular verb. So for regular verbs, we simply add ed. The result is sentences such as, I have played football today, or he has played snooker today.
