The Copula Complement Is Not Marked at All

In some languages the copula complement is not marked at all. You can get different kinds of marking, depending on what exactly is going on in the copula. In a small number of languages, copula complement pronouns like it's me have an entirely separate distinct form. And then once again, getting back to the subject, the copula subject may be quite interesting in the negative finish uses the part of the case.
