Localization of singular/plural words - what are the different language rules for grammatical numbers?

Question

I have been developing a .NET string formatting library to assist with localization of an application. It\'s called SmartFormat and is open-source on GitHub.

Answer 1

Definitely, different languages have different pluralization rules. Especially interesting could be Arabic and Polish both of which contain quite a few plural forms.

If you want to learn more about these rules, please visit Unicode Common Locale Data Repository, namely Language Plural Rules.

There are quite a few interesting information there, unfortunately some of them are unfortunately wrong. I hope plural forms are correct (at least for Polish they are, as far as I could tell :) ).
