Map of nouns to their irregular plural form
An irregular plural in this library is defined as a noun that cannot be made plural by applying these rules:
- If the noun ends in an "s", "x", "z", "ch" or "sh", add "es"
- If the noun ends in a "y" and is preceded by a consonent, drop the "y" and add "ies"
- If the noun ends in a "y" and is preceded by a vowel, add "s"
The list is just a JSON file and can be used wherever.
