「～れば」 form for 「です」


A question came up recently that made me wonder how this form is for the verb
です.

I know that です has a ～たら form that is conjugated as だったら。But, does it have a
～れば form? Is it でれば？ (I don't think so because that's more likely 出れば。) Is it
だれば？ Or is it であれば？ (from である rather than です）

If it is であれば, why is that so?

I know that once I knew this but I seem to have forgotten. Help!




It **is** 〜であれば. This is because です is really just a contraction of であります。 So
you simply take the 〜れば form of あります, which is あれば.

Similarly, the だったら you mentioned is also just a contraction of であったら, and you
can see あったら is just the 〜たら form of あります.
