Esperanto Rules

Esperanto pluralization and singularization rules.

This module defines the complete set of Esperanto pluralization rules used by pluralio. It is imported automatically when import pluralio is executed, which triggers the registration of the eo language in the global registry.

Esperanto has the simplest pluralization system of any language: every noun takes -j to form the plural, and the accusative case adds -n after the plural marker. There are no irregulars, no gender, and no exceptions.

Rules:

• libro → libroj (singular → plural, add j)

• libroj → libro (plural → singular, remove j)

• libron → librojn (accusative singular → accusative plural)

• librojn → libron (accusative plural → accusative singular)

Uncountable words: pronouns and correlatives that do not take plural (mi, vi, li, ŝi, ĝi, ni, ili, oni, si).
