Final answer:
The type of postmarital residence practiced by the Nayar is not specified, but postmarital residence is influenced by societal rules and descent, including patterns such as neolocal, patrilocal, and matrilocal residence.
Step-by-step explanation:
The type of postmarital residence practiced by the Nayar is not explicitly mentioned in the provided references, but we can discuss the general patterns of postmarital residences that are found in different societies. Postmarital residence rules are the social rules that determine where a newly married couple will reside after marriage. These rules are often related to the descent rules of the society. There are several patterns such as neolocal residence, where the couple establishes an independent household; patrilocal residence, where the couple lives with or near the groom's family; and matrilocal residence, where the couple lives with or near the bride's family. Some cultures also practice avunculocal residence, living with or near the groom's maternal uncle, as part of matrilineal descent. Circumstances such as economic need and housing availability can influence these patterns. In the case of the Nayar, more information would be required to determine the specific type of postmarital residence they practice.
