Forms

Fauna f (genitive Faunae); first declension[1][2]

Etymology

It is from Latin Faunus (“a rustic god”), with the feminine ending.[3][4][5] De Vaan lists it among the derivatives of Faunus, which he traces to a Proto-Italic form meaning “favourable”, Proto-Italic *fawe/ono-, from Proto-Indo-European *bʰh₂u-n- (“favourable”), the root also seen in faveō.[6]

Ancient grammarians explained both names from prophesying: Varro says the Fauni foretold the future in verse in the woods, and Servius derives Faunus and Fauna from ⟨fari⟩, “to speak”.[7][8]

Earliest recorded meaning

Varro names her beside Faunus as one of the gods of the Latins, saying that “there is both a Faunus and a Fauna”.[7][5]

Semantic evolution

Later writers made her the sister, wife or daughter of Faunus and identified her with the Bona Dea;[2][4][9] Macrobius and Lactantius report this.[2][4][9] Servius equates her with Fatua.[8]

In the 18th century Linnaeus took the name for the animals of a region, as a companion to Flora, in the title of his Fauna Suecica (1746); English borrowed this sense in 1771.[10]
