Reference is made again to a form of food-money cycle. When a man marries, his wife's younger brothers and sisters are "children" (ngelekel: his child). The husband and wife strive to engage them in from this particular food-money cycle: Father to daughter (wife's younger sister) -food Daughter to father-money Father to son (wife's younger brother)money Son to father-food and service. The saying may be applied to a man who marries or has sexual relations with his wife's sister, thus interrupting or jeopardizing this food-money cycle. With less strength, the sanction is applied to a man marrying any member of his wife's immediate clan (kebliil).
