Questions & Answers about Signatura i izdanje su u katalogu.

Why is the verb su and not je?

Because the subject has two nouns: signatura i izdanje = the call number/signature and the edition.

In Serbian, when two singular nouns are joined by i (and), the verb is usually plural:

• signatura ... je = the call number/signature is
• izdanje ... je = the edition is
• signatura i izdanje ... su = the call number/signature and the edition are

So su is the correct present tense plural form of biti (to be).

What case are signatura and izdanje in?

They are in the nominative singular, because they are the subject of the sentence.

• signatura = nominative singular
• izdanje = nominative singular

Even though the whole subject is plural in meaning because it has two parts, each noun itself stays singular.
