The present perfect tense is used to describe actions that began in the past and have relevance to the present. It is formed using some form of the verb "have" plus the past participle of the main verb. The present perfect can be used to talk about completed past actions at an unspecified time or ongoing actions that began in the past and continue to the present, especially when used with time words like "for" and "since". Common uses include describing experiences, changes in circumstances, or recently completed actions.
