"My gray ruler is in the jar."

Translation: Rigla mea gri e în borcan.

[RAugood]

Why not "rigla gri a mea"?

[dmivapi]

Doesn't 'a mea' mean 'mine' - not 'my'?

[Liz745383]

Why is este not acceptable in this sentence? I dont really understand when i have to use 'e' instead.

They mean the same thing so they are interchangeable but Duo does not think this way.
