ESL Grammar Verbs Tenses Present Perfect Experience Change Continuing Situation

What It Is

The Present Perfect is a grammar point used to talk about experiences, changes, or continuing situations that started in the past and have an effect on the present. It's formed with Subject + have/has + past participle. For example: "I have eaten breakfast" (not "I eat breakfast" because it's not a regular habit). ESL learners often struggle with this topic because it's hard to understand when to use the present perfect and when to use the past simple.
