Kinship terminology in the context of "Consanguine"

In social psychology, an interpersonal relation (or interpersonal relationship) describes a social association, connection, or affiliation between two or more people. It overlaps significantly with the concept of social relations, which are the fundamental unit of analysis within the social sciences. Relations vary in degrees of intimacy, self-disclosure, duration, reciprocity, and power distribution. The main themes or trends of the interpersonal relations are: family, kinship, friendship, love, marriage, business, employment, clubs, neighborhoods, ethical values, support, and solidarity. Interpersonal relations may be regulated by law, custom, or mutual agreement, and form the basis of social groups and societies. They appear when people communicate or act with each other within specific social contexts, and they thrive on equitable and reciprocal compromises.

Interdisciplinary analysis of relationships draws heavily upon the other social sciences, including, but not limited to: anthropology, communication, cultural studies, economics, linguistics, mathematics, political science, social work, and sociology. This scientific analysis had evolved during the 1990s and has become "relationship science", through the research done by Ellen Berscheid and Elaine Hatfield. This interdisciplinary science attempts to provide evidence-based conclusions through the use of data analysis.

Systems of Consanguinity and Affinity of the Human Family is an 1871 book written by Lewis Henry Morgan (1818–1881) and published by the Smithsonian Institution. It is considered foundational for the discipline of anthropology and particularly for the study of human kinship. It was the culmination of decades of research into the variety of kinship terminologies in the world conducted partly through fieldwork and partly through a global survey of kinship terminologies in the languages and cultures of the world.

It "created at a stroke what without exaggeration might be called the seminal concern of contemporary anthropology, the study of kinship..." In the book Morgan argues that all human societies share a basic set of principles for social organization along kinship lines, based on the principles of consanguinity (kinship by blood) and affinity (kinship by marriage). At the same time, he presented a sophisticated schema of social evolution based upon the relationship terms, the categories of kinship, used by peoples around the world. Through his analysis of kinship terms, Morgan discerned that the structure of the family and social institutions develop and change according to a specific sequence.

Hawaiian kinship, also referred to as the generational system, is a kinship terminology system used to define family within languages. Identified by Lewis H. Morgan in his 1871 work Systems of Consanguinity and Affinity of the Human Family, the Hawaiian system is one of the six major kinship systems (Inuit, Hawaiian, Iroquois, Crow, Omaha, and Sudanese).

Sudanese kinship, also referred to as the descriptive system, is a kinship system used to define family. Identified by Lewis Henry Morgan in his 1871 work Systems of Consanguinity and Affinity of the Human Family, the Sudanese system is one of the six major kinship systems (Eskimo, Hawaiian, Iroquois, Crow, Omaha and Sudanese).

The Sudanese kinship system is the most complicated of all kinship systems. It maintains a separate designation for almost every one of Ego's (the individual's) kin, based on their distance from Ego, their relation, and their gender, and in some instances based on relative age. The patrilineal and matrilineal line are differentiated. Ego's father is distinguished from Ego's father's brother and from Ego's mother's brother; Ego's mother is similarly distinguished from Ego's mother's sister and from Ego's father's sister; et cetera. For cousins, there are up to eight possible terms.

In Spanish, grammatical gender is a linguistic feature that affects different types of words and how they agree with each other. It applies to nouns, adjectives, determiners, and pronouns. Every Spanish noun has a specific gender, either masculine or feminine, in the context of a sentence. Generally, nouns referring to males or male animals are masculine, while those referring to females are feminine. In terms of importance, the masculine gender is the default or unmarked, while the feminine gender is marked or distinct.

Many gender-related features are common across Romance languages. However, Spanish differs from other Romance languages, like French and Italian, in its kinship terms. For instance, the Spanish words for "uncle" and "aunt" are tío and tía respectively, while in French, they are oncle and tante. Similarly, the Spanish words for "brother" and "sister" are hermano and hermana, whereas in Italian, they are fratello and sorella.
