why do nouns have gender in some languages
Grammatical gender The division into genders usually correlates to some degree, at least for a certain set of nouns (such as those denoting humans), with some property or properties of the things that particular nouns denote. Such properties include animacy or inanimacy, "humanness" or non-humanness, and biological sex.
Joyce (name) The name Joyce is a contemporary given-name used for females and rarely used by males. As a family-name, it derived from the Old French Masculine name Josse, which derived from the Latin name Iudocus, the Latinized form of the Breton name Judoc meaning "lord". The name became rare after the 14th century, but later revived as a female given-name, which derived from the Middle English joise meaning "rejoice". [1]
