"Αυτοί είναι στο κάστρο."

[jurgen_maes]

αυτή είναι στο κάστρο should also be correct as there is no audible difference between αυτή and αυτοί

[sakinma]

Can this be also "αυτή είναι στο κάστρο"? Or how can we differentiate between αυτοί ή αυτή;

[jaye16]

"Αυτή" is "she" singular a female. "Αυτοί" is plural male or female. If it's written you see it.

But if you hear it in a normal conversation you'll understand by the context.

But if you had this in a listening exercise there is no way to know. So, please tell us if you had it on a listening and we'll report it for removal as it's confusing. Thank you.

[sakinma]

Thanks, yes, it was on a listening exercise. Otherwise, the written parts are quite easy to distinguish. I am simply not very familiar with how things are organized in a course and automatically thought that this was only a listening exercise.

[jaye16]

Thank you, I'm suggesting that these "αυτή" or "αυτοί" sentences, and other similar, not be used on the listening. I've reported this for review. Thanks for your cooperation it helps a lot.

Just encountered this one - 8 months on from the original discussion about it. In other words I got it in a listening exercise, wrote "αυτή" and it was marked wrong.

I just had the sentence in a listening exercice.
I wrote: αυτή είναι στο κάστρο.
It was not accepted

[Dimitra956826]

I'm afraid so. It's a common problem with homophones. We can't fix this issue ourselves, so... We hope that it will be fixed, somewhere in the near future. :/ Thank you for your comment though. ^.^

[Georgiaonc]

It's still happening in the listening exercise on Strengthen Skills////But I like the new format

[Dimitra956826]

Yes, homophones are still an issue, unfortunately. :/ The cases are only a few compared to the existing sentences, but we are trying to figure out how to solve this one (with some Duolingo help, of course. ^.^)

[Georgiaonc]

Just keeping you amazing people posted... You are doing a great service ...my Greek has never been better...so long as I keep on using Duolingo!!

[jaye16]

Thank you very much. That's so good to hear.

[doconnor80]

Could this also be They are at the castle?

[jaye16]

Yes, and we'll add it to the Incubator. Thank you.

[mandrivnytsia]

This issue still hasn't been solved :( I wrote "Αυτή είναι στο κάστρο" and it was wrong :( In a listening exercise there's no way to know whether it's "she" or "they"...

[jaye16]

I have removed the sentence from the listening test.
