- (rare, chiefly archaic) A miscellany.
- Miscellanea is almost universally treated as a plurale tantum in English, consequently, the singular form miscellaneum is liable to cause confusion:
- As miscellanea means, in the usual sense, “a miscellaneous collection of different things”, a single miscellaneum is logically impossible because variety and diversity (in their usual senses) are attributes of groups of things, not of individual things; for example, a populace can be varied and diverse, but a person cannot be various or diverse.
- Miscellanea will usually be taken to mean “a single miscellany”, not several assortments.
- In common usage, miscellany is over seven hundred times more common than miscellaneum , whereas miscellanea is around six hundred times more common than miscellaneum ; in re plural forms, the Anglicised miscellaneums is well over a hundred thousand times rarer than miscellanea and over eighteen thousand times rarer than miscellanies .
Perhaps by back-formation from miscellanea, in accordance with the -um → -a rule of plural formation of neuter nouns in the nominative case from the Latin second declension.
