Sometimes the sex of a word changes over time. For example, the modern Russian motto “whisky” was originally feminine,[40] then masculine,[41] and today it has become neutered. Articles, possessive and other determinants also decrease in number and (only in the singular) for sex, the plural determinants being the same for both sexes. This usually produces three forms: one for the singular male nouns, the other for the female singular nouns and the other for the plural substitutions of one of the two sexes: a name may belong to a particular class because of the characteristics of its reference point, such as sex, animacy, form, although in some cases a noun can be placed in a given class. , based exclusively on his grammatical behaviour. Some authors use the term “grammatical gender” as a synonym for “nominal class,” while others use different definitions for each. Substantive cognate in closely related languages probably have the same sex because they tend to inherit the sex of the original word in the language of the parents. In Romance languages, the words for “sun” are masculine and are derived from Latin male names, while the words for “moon” are feminine and are derived from the female Latin Luna. (This contrasts with the sexes in German, where the sun is feminine, and the moon “moon” is male, as well as in other Germanic languages.) There are, however, exceptions to this principle. For example, latte (“milk”) is masculine in Italian (like French milk and Portuguese leite), while Spanish leche is castrated as female and Romanian latte. Similarly, the word for “boat” in German is neutered (the boat), but the usual sex in Swedish (in b`t). The agreement is one of those basic areas of English grammar with which many advanced learners, such as commas and capital letters, still regularly make mistakes.

Part of the reason is probably that the concept of agreement actually covers a fairly wide range of different structures. As a result, different aspects are usually presented at different times, making it more difficult for learners to make useful connections between them, and there are many places where errors are likely. The grammatical sex of a no bite does not always correspond to its natural sex. An example is the German word for girl; this derives from the maid “maiden” as a “girl” with the small suffix, and this suffix always makes the no bite with grammatically castration. Therefore, the grammatical sex of girls is neutered, although its natural sex is female (because it refers to a woman). In male and female languages, males are generally used by default to refer to people of unknown sex and mixed sex groups. Thus, the female plural pronoun in French always refers to a purely female group of human beings (or represents a group of subtantifs of the entire female sex), but the male equivalent may refer to a group of male men or sub-combatants, a mixed group or a group of persons of unknown sex. In these cases, it is said that the female sex is marked semantically while the male sex is not marked. In Dravidian languages, names are classified mainly on the basis of their semantic properties. The highest classification of nouns is often described as “rational” and “non-rational.” [50] Nouns representing humans and human beings are considered rational, and other nouns (which represent animals and objects) are considered non-rational. Within the rational class, there are other subdivisions in male, female and collective names. For more information, see Tamil Grammar.
