"Мой дедушка сейчас играет на скрипке."

Translation: My grandfather is playing the violin now.

[Nicole718932]

Can this not be translated as "My grandfather is currently playing the violin"?

[AidenCotnam]

That should work, as «сейчас» refers to something at the present time.

[buynpass2]

I had put "My grandpa is playing the violin right now"--I think that's also an acceptable answer

[olimo]

Report it. "Right now" is "прямо сейчас", though.

[HudayfaTulu]

Guys, what is the true translation of "Granddad" into Russian?

[anothernobody]

Is this in the Prepositional, or the Dative (when you play an instrument)? What about games, board games, sports?

[keinemeinung]

Instruments are put into prepositional (на гитаре, на скрипке), games/sports are accusative (в футбол, в карты).

[alex925070]

How on earth can "My grandfather is now playing the guitar" be incorrect but "My grandfather is playing the guitar now" is correct? They mean exactly the same thing.

[Kundoo]

Both are incorrect, because it's a violin, not a guitar.
