Questions & Answers about Μην ξεχάσεις το φλας πριν στρίψεις δεξιά.
It is a negative command: someone is telling one person not to forget something.
More specifically, it is:
- informal
- addressed to you (singular)
- about a single action in the future
So the tone is like: Don’t forget the indicator before you turn right.
Because δεν and μην do different jobs:
- δεν negates statements
- μην negates subjunctive forms, including negative commands
So:
- Δεν ξεχνάς το φλας = You are not forgetting the indicator / You don’t forget the indicator
- Μην ξεχάσεις το φλας = Don’t forget the indicator
In English, both might use not/don’t, but Greek makes a clear distinction.
