Pluralisation is handled via a set of rules. They aren't perfect but last time I checked bugs are not accepted against these rules because it would be too easy to break apps that depending on the previous pluralisation (and equally it's difficult to be sure that you're not introducing new pluralization errors)

You can add your own rules though - see http://api.rubyonrails.org/classes/ActiveSupport/Inflector/Inflections.html
