"I have very little time."

Translation: Mam bardzo mało czasu.

[amnae]

Mało needs genitive?

[Jellei]

Yes, you're right.

[PVLSANS]

Can't I use "pory"?

[Jellei]

No. "pora" is some specific time (like "wieczór" is "pora dnia" - evening is a time of the day), it's not used to measure time.

[ConeyBundock]

can you say, Mam bardzo trochę czasu.

[Jellei]

Not really, or as a strange language joke. It's like saying "I have very some time".

[eggers7]

"mało" is adverb, right? Why is an adverb used to serve as a direct object?

[Jellei]

I'm far from being an expert on syntax, but I believe that here "mało" is an indefinite numeral. But yes, it can also be an adverb.

[ivaigult]

Would it be correct to say "Mam za mało czasu?"

[Jellei]

It's a correct sentence that means something different, i.e. "I have too little time".

"very little time" may still be enough time.
