Wow, Duo literally bamboozled me, there was Omar and Oman in the word choices...
Excellent is also correct and you said it's wrong....
Duo has misspelled the word neighbour. (Neighbour )
American spelling not always up to English standard.
My sentece is correct but you said its wrong.
Why is neighbour/ jarik said as female here?
Because you are talking to Rania, who is female. "jaarik" means "your neighbour", when talking to someone who is female.
Its your technical fault ,not mine
NeighboUr is wrong?
Neighbour is correct, but Duo prefers American English. You can submit your translation claiming is should be accepted.
Omar is apparently both a doctor and a translator, and is everyone's neighbour. Whew!
I think jarik should be male jarak .
