Common gender divisions include masculine and feminine; masculine, feminine, and neuter; or animate and inanimate. In a few languages, the gender assignment of nouns is solely determined by their meaning or attributes, like biological sex, humanness, or animacy. However, in most languages, this semantic division is only partially valid, and many nouns may belong to a gender category that contrasts with their meaning (e.g. the word for "manliness" could be of feminine gender). In this case, the gender assignment can also be influenced by the morphology or phonology of the noun, or in some cases can be apparently arbitrary.
