pluralization is much MUCH more complex in many languages than in English: https://www.unicode.org/cldr/charts/47/supplemental/language...

it can largely be turned into six categories of behavior, with tons of languages choosing different boundaries for those categories. ios/osx and android have tools for this, and probably others (I'm just personally familiar with these).

and even English isn't even that simple in the way many treat it - you don't pluralize sentences, parts of sentences change in contrast to each other (a car drives vs cars drive). so e.g. widely used APIs like https://apidock.com/rails/v7.1.3.4/String/pluralize are blatantly misleading merely by existing, and it leads to mistakes in many (most?) languages, and also English, even though the authors of the API speak English.

That has to be one of the most cursed functions that I've heard of in my life. Anything less than a call to ChatGPT is doomed to fail.
