Pronunciation

  • Classical: [ˈmaːr.ti.ʊs][1]
  • Ecclesiastical: [ˈmar.t͡si.us][1]

Forms

Mārtius (feminine Mārtia, neuter Mārtium); first/second-declension adjective[1]

Etymology

It is formed from Latin Mārs + -ius; as a noun meaning March it is short for the phrase with mēnsis (“month”).[1] De Vaan lists it among the derivatives of the god's name, which developed within Latin from older ⟨māmart-⟩, attested on the Lapis Satricanus, through ⟨Māvort-⟩ to ⟨Mārt-⟩;[2] Umbrian has an adjective of the same kind, Umbrian marties (“of Mars”).[2]

The month name is the source of English March, through Anglo-French and Old French marz, and of Spanish marzo, Portuguese março, Italian marzo, German März and Dutch Maart.[3]

Earliest recorded meaning

De Vaan's first records are an inscription, CIL 1.1513, which speaks of money from the spoils of war (aere Martio), and Varro.[2][4] The OLD's earliest quotation for the month is from the comic poet Atta, who says that March was meant to be the first month: uoluerunt esse primum mensem Martium.[4]

Semantic evolution

It meant belonging to or sacred to Mars: the woodpecker was picus Martius, the wolf Martius lupus, and the Campus Martius was the plain of Mars outside Rome where the assemblies met.[4][5] A legion was named the legio Martia.[4] With mensis or alone it was March, originally the first month of the year, and as an adjective “of March”, as in the calends, nones and ides of March.[4][5] Poets used it for “Roman”, since Mars was the ancestor of the Romans,[4][5] and it also meant warlike, martial, and belonging to the planet Mars.[4]

In medieval Latin the noun Martius is March,[6][7] and in British sources the adjective is still used of war and of the woodpecker.[8]
