On what basis is this form of the plural classified as NONSTANDARD?211.225.37.47 23:05, 10 September 2009 (UTC)


 * Because it’s a “double plural”. It derives from a neuter noun of the Latin second declension ending in -um:, whose etymologically-consistent plural form terminates in -a: (as ). If it derived from a feminine first-declension Latin noun like *undefined:, then the etymologically-consistent plural would indeed be *undefined:.
