Etymology

It is inherited from Proto-Italic *anamo- (“breath, spirit”), inherited from Proto-Indo-European *h₂enh₁-mo- (“breath”), from the root Proto-Indo-European *h₂enh₁- (“to breathe”).[2][1] Cognate with Oscan anamúm (“breath, spirit”), Old Irish anim (“soul”), Ancient Greek ἄνεμος (ánemos, “wind”) and Armenian հողմ (hołm, “wind”).[2][1][3]

Earliest recorded meaning

Plautus uses it.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

In Classical Latin it was the mind or soul as opposed to the body, and the element of air as the principle of life.[3] It was the seat of consciousness, thought, attention and intention (in animō habēre “to intend”), of desire and will, and of feelings such as grief, pleasure, anger, pride and courage.[3] It also meant a person's disposition and character, as Ennius' “o devotion of mind”.[3] Döderlein says anima is the soul as the principle of life, which ceases with the breath, while animus is the soul as the seat of thought and will.[5]

In medieval Latin it was the mind, the spirit and the inner self, and character, courage, pride, purpose or animosity.[6][7] It was borrowed as Italian animo and Spanish ánimo.[1] English animosity comes from animōsus, and English borrowed animus in 1820.[8]

  • c. 250–184 BC – Plautus uses it of the mind.[3][4]
  • 204–169 BC – Ennius uses it of grief and of character.[3][4]
  • early 15th century – English animosity is recorded, first as “bravery”.[8]
  • 1820 – English animus is recorded as “temper”.[8]
