"Nem volt ott."

Translation: She was not there.

[Panchete1]

Volt = it was/ there was. You can listen this word in this song by Neoton Familia (the magyar ABBA :P) : https://www.youtube.com/watch?v=XyOlnPcakEk

“He or she was not there” is correct as well, and should be accepted. I am reporting it.

[jzsuzsi]

Don't report it. Duolingo accepts It was not there/ He was not there /She was not there. The "he or she" variant is not needed.

[Zsuzsi97194]

Then why was I marked wrong for using she?

[ThomasWilm13]

I said he wasn't there . Not accepted

[Istorik1129]

Yep! The "it" is implied by verbs in the definite conjugation. Thanks for introducing us to the Neoton Família!

[RyagonIV]

There is no definite conjugation here. Van can't even take definite forms since it's not a transitive verb. Volt simply is the third person singular past conjugation and the subject is implied.
