LYK vs LMK
Many people confuse LYK with LMK because both contain similar words.
Here’s the difference:

| LMK | Let Me Know | Please tell me or inform me. | The other person |

Meaning:
Please tell me when you arrive.
Easy Way to Remember
Think of it like this:
- LYK = I will tell you.

1. Confusing LYK with LMK
This is by far the most common error.

Correct
LMK when you get home.
2. Using LYK in Formal Writing
