Step-by-step explanation:
According to Edmund Leach, marriage can accomplish several things, but it is not always guaranteed to do so. One of the things marriages can accomplish is establishing a legally recognized contract between two people, traditionally based on a sexual relationship and implying a permanence of the union. Another thing that marriage can accomplish is giving either or both spouses rights over the other's property. Lastly, marriage can establish a socially significant "relationship of affinity" between spouses and their relatives.
