In EnglishMukuwasha, also written mukwasha, is a daughter's husband, the son-in-law, who owes his wife's family lifelong help and respect.
Mukuwasha is the man who has married a family's daughter; her brothers, sisters and grandparents also count him as their mukuwasha, and a Shona dictionary adds that the man who marries your sister is your mukuwasha too. His marriage begins with roora: he sends a go-between (munyai) to announce his intentions, brings the groceries the bride's family lists, matching the list exactly as a sign of respect, and pays in stages until he is welcomed into the home, greeting his new in-laws with the gusvi clap.
His duties do not end with the payments. Custom required him to sweep the ashes at his in-laws' dare once negotiations had begun, to greet his parents-in-law first whenever they meet, never to visit them empty-handed, and to help in times of joy and hardship: building houses, leading threshing work parties, and taking a central, organising part at his in-laws' ceremonies and funerals. He speaks to his vatezvara and ambuya in the respectful register (chinyarikani).
