Present Perfect vs. Past Simple

Understanding the difference between the present perfect vs. past simple tenses is essential for mastering English grammar. Both tenses are used to talk about past events, but they serve different purposes and convey different nuances.

• They have just arrived. (Recent action with a present effect)

What is the Past Simple Tense?

The past simple tense is used to describe actions or events that were completed at a specific time in the past. It is formed by adding “-ed” to the base form of regular verbs or using the second form of irregular verbs.
