What’s the Difference Between the Present Perfect and the Past Simple?

1. Understanding the Past Simple
The past simple is used to talk about actions that happened at a specific time in the past. The time can be mentioned explicitly or understood from the context.
Examples:
- I visited London last year.
- She watched a movie yesterday.
- They finished the project in 2022.
Key tip: Past simple = completed actions at a definite time.

2. Understanding the Present Perfect
The present perfect is used for past actions connected to the present. Often, the exact time is not mentioned.
Examples:
- I have visited London several times.
- She has watched that movie before.
- They have finished the project already.
Key tip: Present perfect = experience or actions relevant now.

3. Visualizing the Difference
Imagine a simple timeline:
- Past simple: A single dot — a finished action at a specific moment.
- Present perfect: A line or multiple dots leading to now — past experience or actions affecting the present.
Example:
- Past simple: “I saw that film last week.” → Done and finished.
- Present perfect: “I have seen that film.” → Part of your experience now.

4. Common Mistakes to Avoid
- ❌ I have visited London last year. → ✅ I visited London last year.
- ❌ She watched that movie before. → ✅ She has watched that movie before.
Tip: Use past simple with specific past times; use present perfect when time is unspecified or relevant now.
