Final answer:
The term 'affinals' refers to a person's in-laws or the family they become related to through marriage.
Step-by-step explanation:
Another name for a person's "in-laws" is affinals. This term refers to the family that an individual becomes related to through marriage. For example, one's mother-in-law or father-in-law are considered affinal ties, as the relationship is established not by blood but through the contractual agreement of marriage, depicted as a double line on a kinship chart. The various forms of kinship systems, such as lineal kinship and bifurcate merging kinship, help anthropologists and social scientists understand the complex social structures within different cultures and how individuals relate to one another within those structures.=
