Definition of genus

Thanks for using this online dictionary, we have been helping millions of people improve their use of the english language with its free online services. English definition of genus is as below...

Genus (n.) 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..
