"You are a physicist."

Translation: Ești fizician.

[bluchill]

So now the "un" is optional? Arrgghhh

[Lurch_M]

When you talk about someone's profession, you usually omit the "un" article. For example: "I'm a doctor" would become "Eu sunt doctor" in Romanian.

[alexander-ua]

Shouldn't the "Tu e fizician" be accepted here?

[Lurch_M]

Nope, but "Tu ești fizician." should.

e is short for este not esti (apologies for lack of accents).
