Questions & Answers about Η μαμά μου λέει να παίρνω μπουφάν και καπέλο όταν φυσάει.
Both are possible, but they mean slightly different things:
λέει να παίρνω (present subjunctive) = she tells me to take (a jacket and hat) as a general habit, regularly.
- This fits a rule your mom repeats: “whenever it’s windy, you should be taking a jacket and hat.”
λέει να πάρω (aorist subjunctive) = she tells me to take (them) on one specific occasion.
- Example: Right now it’s windy and you’re going out: Η μαμά μου λέει να πάρω μπουφάν και καπέλο. = My mom is telling me (now) to take a jacket and hat.
So να παίρνω emphasizes a repeated / habitual action, while να πάρω emphasizes a single, whole action. In this sentence, να παίρνω matches the idea “whenever it’s windy, as a rule.”
