"I slept for nine hours."

Translation: Saya tidur sembilan jam.

[Bratsche2]

Why selama?

[Ceri947554]

It is the word 'for' before a time

I tried “Saya sudah tidur selama sembilan jam.” It was incorrect. I thought ‘sudah’ to indicate past tense, and while not strictly necessary is it wrong per say? Or does my sentence mean something different? Thanks, Indon gurus!

Either "untuk" or "selama" is correct here. This needs to be updated to allow those answers.
