In the Etruscan language, plural nouns were formed by adding one of the plural markers—ar, er, or ur—to the word stem.1

When these nouns were declined, the case endings were added to the stem along with one of these plural markers. Notably, the case endings themselves did not differ between the singular and plural forms.1
