In Classical Latin textbooks the declensions are named from the letter ending the stem or First, Second, etc. to Fifth. A declension may be illustrated by a paradigm, or listing of all the cases of a typical word. This method is less frequently applied to Old Latin, and with less validity. In contrast to Classical Latin, Old Latin reflects the evolution of the language from an unknown hypothetical ancestor spoken in Latium. The endings are multiple. Their use depends on time and locality. Any paradigm selected would be subject to these constraints and if applied to the language universally would result in false constructs, hypothetical words not attested in the Old Latin corpus. Nevertheless, the endings are illustrated below by quasi-classical paradigms. Alternative endings from different stages of development are given, but they may not be attested for the word of the paradigm. For example, in the second declension, *"campoe" "fields" is unattested, but "poploe" "peoples" is attested.
