ignis

Etymology and origin of the Latin word ignis

History

Pronunciation

  • IPA (Classical): [ˈɪŋ.nɪs][1]
  • IPA (Ecclesiastical): [ˈiɲ.ɲis][1]

Forms

ignis m (genitive ignis); third declension[1] The ablative singular is igni or igne;[2] igni alone is found in the older texts, and igne from the time of Caesar.[3] Inscriptions and manuscripts also spell it ingnis.[3][4]

Etymology

It is inherited from Proto-Italic *n̥gʷni- (“fire”), inherited from Proto-Indo-European *h₁n̥gʷnís (“fire”).[5][1] De Vaan traces the development through the stages *Hn̥gʷni- > *Həngni- > *engni-, which became egni- (or ingni-) by dissimilation.[5] The word replaced the inherited Italic word for fire, *pūr.[1]

Cognate with Sanskrit अग्नि (agní-, “fire”), Lithuanian ugnis and Old Church Slavonic огнь (ognĭ).[5][2][6] Varro derived it from being born (nāscī), and Isidore of Seville because nothing can be born of it.[3]

Earliest recorded meaning

Its first record is in the Twelve Tables of about 450 BC,[5][4] and from early Latin on it means fire, whether a single blaze or fire in general.[2]

Semantic evolution

Besides fire as a process, the word named fire as one of the four elements,[2] the domestic fire that with water stood for the necessities of life, the fire of the altar and the eternal fire of Vesta,[2] and fire used for signals, torture, cremation and destruction.[2] It was applied to the fire of the sun, the stars and lightning, to the glow of jewels and eyes,[2] and to fever;[2] ignis sacer was a name for skin diseases such as erysipelas.[2] Poets used it for the fire of love, and even for the person loved, and for anger or high spirit.[2]

In Church Latin the plural could mean the desires of the flesh,[7] and in medieval Latin it stood for a hearth or household and for the right to gather firewood.[8][4] The everyday word for fire, however, became focus, first “hearth”, which took over the sense “fire” in Late Latin.[9][8]
