Breakdown of Προσπαθώ να παίρνω πρωτοβουλία στο μάθημα ελληνικών, ακόμα κι αν κάνω λάθη.

Why is it να παίρνω and not να πάρω?

Greek makes a strong distinction between imperfective and perfective aspect, even in the subjunctive.

να παίρνω (imperfective) = to take initiative regularly, as a habit, in general
να πάρω (perfective) = to take initiative once / in one specific instance

In this sentence, the idea is:

I’m trying in general, as a rule to take initiative in Greek class.

That’s why the imperfective form παίρνω is used.
If you said:

it would sound more like:

I’m trying to take the initiative (this time / in a particular situation) in Greek class…

So να παίρνω matches a repeated, ongoing effort; να πάρω would focus on a single act.

What exactly does πρωτοβουλία mean, and is it countable?
