Natural gender
Natural gender is a linguistic category for the sex of real life beings, be it the biological sex of animals or the social identity of a person. The sex, of humans and animals, can be marked in many languages by a corresponding grammatical gender and specific words. The term sex (or sexus) does not apply to words that do not refer to living things (for example: the word "table" is grammatically feminine in Spanish, but tables are not "feminine"), which are called inanimate beings. The gender of words, on the other hand, serves to divide words into grammatical classes (into genders), which require a language for all nouns.
