/əˈfɪn.ə.ti/ – Noun
Definition: 1. quan hệ thân thuộc do hôn nhân mà có;
2. người thân thích (bên chồng hay bên vợ).
A more thorough explanation: In legal terms, “affinity” refers to a close relationship by marriage rather than by blood, such as the relationship between a person and their spouse’s relatives. It is a legal concept used to describe the relationship between a person and the relatives of their spouse.
Example: The defendant argued that there was no evidence of any affinity between the two companies, therefore the contract could not be enforced.
