Avunculocal refers to a type of residence where a married couple lives with or near the husband's uncle or maternal uncle. This term originates from the Latin word avunculus, which means "maternal uncle." However, several synonyms can replace the term if you want a more specific or complex understanding of the living arrangement. One synonym that closely resembles avunculocal is matrilocality, a type of residence where a married couple stays with or near the wife's mother's family. It's the opposite of patrilocality, where a couple moves in with or near the husband's father's kin. Another synonym that you can use is bilocality, which refers to a more flexible residence system where a couple can choose to live with either of their families, depending on their needs or preferences. This system is common among hunter-gathering societies.
