TAKOBOTO

いしゃであるたなかさん

The Tanaka san who is a doctor.

そうであるとしても、このばあいはべつでしょう。

Even if that is correct, would it not have to be different in this case?

いつもしょうじきであるということは、よういなことではない。

To be always honest is not easy.

我輩は猫である。

I don't see why である is being distinguished from だ even though ではない is included on the page for だ. Furthermore, several forms have been missed, such as でない (traditional negative form of である) as well as であろう (traditional negative form of darou).

Eeker

Usually used in written, formal works.

Amatuka

One way in which である (dearu) can be used where だ (da) cannot is to modify nouns.
e.g. 医者である田中さん (senshu de aru tanakasan) The Tanakasan who is a doctor.

Amatuka

roma-ji is wrong for e.g. in user comments.
医者である田中さん(isha de aru tanaka-san)

I agree with Eeker. It would be better remove English meaning of (formal equivalent of だ [da]).

Miki

I think de aru is found in formal written texts. Thesis, abstracts, conference text, just to name a few examples.
