Why is it not: "Τι πρέπω να κάνω;"?

[G.Georgopoulos]

"Πρέπει" is an impersonal verb. Πρέπει να+conjugated verb.

[NancyWalke13]

So literally it is more: What is necessary for me to do?

[Jerry503405]

Is it possible to consider this as "What am I sopposed to do"?

[G.Georgopoulos]

"Τι υποτίθεται ότι πρέπει να κάνω;"

[I.Schmidt1]

what have i to do
is the same?

[mizinamo]

I'd say that as: What do I have to do?

But yes, I'd say that is also a meaning of the Greek sentence.

And it's an accepted alternative, together with "What must I do?".

[Nikos48739]

What should I make?

[G.Georgopoulos]

That's one of the accepted translations as well.
