Common mistakes to avoid
1. I have seen him yesterday ❌
Do not use the Present Perfect with a finished time (yesterday, last week, in 2020, two days ago). Use the Past Simple: I saw him yesterday. With decide, use decided with a finished time and have decided without one.
2. I live here since 2020 ❌
Some situations started in the past and are still true now. For them, use the Present Perfect: I have lived here since 2020, I have known her for three years. Use since + a starting point (since Monday, since 2020). Use for + a length of time (for two weeks, for a long time).
3. He have decided ❌
With he, she and it, use has, not have: he has decided, my friend has decided. The short form is he's decided. Careful: here 's means has, not is.
