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 swell, use swelled with a finished time and have swollen 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. I have swelled ❌
After have or has, use the past participle, not the Past Simple: I have swollen. The Past Simple of swell is swelled, and the past participle is swollen. Learn the three forms together: swell, swelled, swollen.
