Wikipedia has an article on:


Borrowed from Latin nummus.


nummus (plural nummi)

  1. (historical) Any of a range of low-value copper coins issued by the Roman and Byzantine empires during Late Antiquity.


Alternative forms[edit]


From νοῦμμος (noûmmos), Doric version of Ancient Greek νόμος (nómos). Confer with numerus, from the same root.



nummus m (genitive nummī); second declension

  1. a coin, piece of money

Usage notes[edit]

Some works ascribe this name to a particular Roman coin, such as the sesterce, but it is unclear which coin was ever known by this name in Latin.


  • The expected form for the genitive plural nummōrum is often written nummum instead in Classical Latin.

Second declension.

Case Singular Plural
nominative nummus nummī
genitive nummī nummōrum
dative nummō nummīs
accusative nummum nummōs
ablative nummō nummīs
vocative numme nummī
