How would you say "my brother and I are good tennis players" in MSA?
This is one of the sentences I have in my study deck:

My brother and I are good tennis players
أَخِي وَ أَنَا لاَعِبِي تِنِسٍ جَيّدِينَ

I am just wondering if this is correct? Shouldn't it be:
اخي و أنا لاعبا تنس جيدان

Since laa3iba onwards is the khabr, and it needs to match the mubtada in duality?

I would appreciate any help!

Answer

I believe the second sentence is correct but not the first one. 
أخي و أنا لاعبا تنس جيدان( is the correct one)
so here أخي is the subject "مبتدأ"
And "لاعبا  " is the predicate" خبر"
And " جيدان" is the adjective" صفة" which must always follow the preceding noun. That's why it's " جيدان" not " جيدين"...

Answer

أخي وأنا لاعبا تنس جيدان ..هذه هي الجملة الصحيحة ..

Answer

أنا   و اخي   لاعبا   تنس  جيدان
