This week’s mistake is one that many English learners make, especially when talking about long-term friendships!
You should never say „I know him since 2015.“ The correct phrase is „I have known him since 2015.“
In English, when talking about how long you have known someone, you must use the present perfect tense (have known) instead of the simple present (know). This is because the action started in the past and is still true now.
Example:
- Incorrect: I know him since high school.
- Correct: I have known him since high school.
Here’s the correct response to a typical question below:
A: How long have you known Tom?
B: I have known him since university!
