Fragment of a discussion from Translating talk:MediaWiki
From what I've understood,
the current message doesn't address languages having 2 plural forms (+1 singular).
So, the solution in this case would be to accommodate a language which has special plurals for numbers ending in '1'.
But only [2-9]1.

Or this, MDN:Plurals
