.declension(singular, plural, count) ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

A poor man's pluralize. Given two declensions, one singular and one plural, as well as a count, this will pick the correct declension. This way we can generate grammatically correct error message.

Parameters:

  • singular (String) —

    The singular form of the word

  • plural (String) —

    The plural form of the word

  • count (Integer) —

    The number of items
