genus n (genitive generis); third declension[1]
Etymology
It is inherited from Proto-Italic *genos, inherited from Proto-Indo-European *ǵénh₁os (“race, offspring”), from the root Proto-Indo-European *ǵenh₁- (“to beget, produce”), the root of gignō and gēns.[2][1] The genitive generis comes from *genes-os by the change of /s/ to /r/ between vowels.[1] Cognate with Sanskrit जन (jána, “race, people”) and Ancient Greek γένος (génos, “race, kind”), and with Gaulish personal names such as Gaulish Cintugenus.[3][4][2]
Earliest recorded meaning
De Vaan and Köbler give Naevius first.[2][5] Köbler dates Naevius c. 235–200 BC.[5] In Plautus it is already birth or descent: a character says he was born of the highest stock.[3]
Semantic evolution
Its first sense was descent, birth or origin, often with the idea of noble birth, and concretely a family or line.[3] It also meant offspring, a nation or race, a generation, and an order of living creatures, genus hūmānum was the human race.[3] In philosophy it became a class containing several kinds, and generally any kind, variety or sort of animals, things or abstract matters.[3] Grammarians used it of grammatical gender.[1]
Varro, as the TLL reports, said that genus was named from begetting, because whatever begets or is begotten can be called a genus.[4] Döderlein groups it with stirps and gēns as words for a race seen in the ascending line, the ancestors.[6] In medieval British Latin it was stock, lineage and family.[7] English took genus as a term of logic in the 1550s and as a biological rank about 1600.[8]
