"Εγώ δεν ξέρω αυτή την πληροφορία."

Translation: I do not know this information.

[HellasCad]

Αυτήν should not be rejected as incorrect.

[Phil682961]

Except in the exercise where you're transcribing from the Greek audio, because the speaker definitely says αυτή not αυτήν.

[MattHaythem]

How is the singular "πληροφορία" used in Greek compared to its plural? Does it refer to a single fact or idea?

[Dimitra956826]

Yes. Πληροφορία usually refers to a single fact, whereas πληροφορίες refers to multiple ones, or information in general. ^.^

[johndelaroo]

Surely: Εγώ δεν ήξερα αυτή την πληροφορία. = "I didn't know this information" would make more sense, since the information must now be known to the speaker?

[Dimitra956826]

Or maybe the first speaker just asked the second one if he knows something about a certain topic, and he replies that he doesn't know anything about it, so the information is still unknown. No? ^.^

[johndelaroo]

Yes, that would be possible.

[Condorandi]

I hear "δε" instead of "δεν" in the recording

[D_..]

I see why you'd think that. In fact what happens is this: the -ν merges in a funny way with ξ- resulting in δε-γκζέρω. I know, right?!
A tip: the audio files are created with text-to-speech software so the voice will pronounce everything that's written. For a listening exercise where you're not sure what you've heard, you meed to also factor in the rules: here, the ruel is that the final -ν is always present (i.e. not dropped) before ξ.

[Condorandi]

The reason of my question was precisely that. I learned very carefully that the "ν" is kept before the "ξ" so I was confused when the bot did not pronounce it.

[D_..]

To be clear, the bot pronunciation in this phrase is very good, very life-like.
