2. Logic. a class or group of individuals, or of species of individuals.
3. a kind; sort; class.

  1. Biology A taxonomic category ranking below a family and above a species and generally consisting of a group of species exhibiting similar characteristics. In taxonomic nomenclature the genus name is used, either alone or followed by a Latin adjective or epithet, to form the name of a species. See Table at taxonomy.
  2. Logic A class of objects divided into subordinate species having certain common attributes.
  3. A class, group, or kind with common attributes.

[Latin, kind; see genə- in Indo-European roots.]

Genus

Ge"nus\ (j[=e]"n[u^]s), n.; pl. Genera. [L., birth, race, kind, sort; akin to Gr. ?. See Gender, and cf. Benign.]

1. (Logic) A class of objects divided into several subordinate species; a class more extensive than a species; a precisely defined and exactly divided class; one of the five predicable conceptions, or sorts of terms.

2. (Biol.) An assemblage of species, having so many fundamental points of structure in common, that in the judgment of competent scientists, they may receive a common substantive name. A genus is not necessarily the lowest definable group of species, for it may often be divided into several subgenera. In proportion as its definition is exact, it is natural genus; if its definition can not be made clear, it is more or less an artificial genus.

Note: Thus in the animal kingdom the lion, leopard, tiger, cat, and panther are species of the Cat kind or genus, while in the vegetable kingdom all the species of oak form a single genus. Some genera are represented by a multitude of species, as Solanum (Nightshade) and Carex (Sedge), others by few, and some by only one known species.

Subaltern genus (Logic), a genus which may be a species of a higher genus, as the genus denoted by quadruped, which is also a species of mammal.

Summum genus [L.] (Logic), the highest genus; a genus which can not be classed as a species, as being.
Language Translation for : genus
Spanish: género,
German: das Genus, das Geschlecht,
Japanese:

genus [(jee-nuhs)]

In biology, the classification lower than a family and higher than a species. Wolves belong to the same genus as dogs. Foxes belong to a different genus from that of dogs and wolves, but to the same family. (See Linnean classification.)


genus 
(pl. genera), 1551 as a term of logic (biological sense dates from 1608), from L. genus (gen. generis) "race, stock, kind," cognate with Gk. genos "race, kind," and gonos "birth, offspring, stock," from PIE base *gen-/*gon-/*gn- "produce, beget, be born" (cf. Skt. janati "begets, bears," janah "race," jatah "born;" Avestan zizanenti "they bear;" Gk. gignesthai "to become, happen;" L. gignere "to beget," gnasci "to be born," genius "procreative divinity, inborn tutelary spirit, innate quality," ingenium "inborn character," germen "shoot, bud, embryo, germ;" Lith. gentis "kinsmen;" Goth. kuni "race;" O.E. cennan "beget, create;" O.H.G. kind "child;" O.Ir. ro-genar "I was born;" Welsh geni "to be born").
