Pluralization Rules
Intro
The following pluralization rules are currently defined in polyquack/rules.py. All language-to-rule mappings are defined in the PLURALIZATION_BY_LANGUAGE dict. If you find a missing language, or any problems with any of the rules, open an issue on GitLab.
They are delimited by semi-colons (;), and you will hopefully find them readable, as they can be difficult to follow.
