The traditional Romanies place a high value on the extended family. Virginity is essential in unmarried women. Both men and women often marry young; there has been controversy in several countries over the Romani practice of child marriage. Romani law establishes that the man’s family must pay a bride price to the bride’s parents, but only traditional families still follow this rule.
Romani social behavior is strictly regulated by Hindu purity laws (“marime” or “marhime”), still respected by most Roma (and by most older generations of Sinti). This regulation affects many aspects of life, and is applied to actions, people and things: parts of the human body are considered impure: the genital organs (because they produce emissions), as well as the rest of the lower body. Clothes for the lower body, as well as the clothes of menstruating women, are washed separately. Items used for eating are also washed in a different place. Childbirth is considered impure, and must occur outside the dwelling place. The mother is considered impure for forty days after giving birth.
Death is considered impure, and affects the whole family of the dead, who remain impure for a period of time. In contrast to the practice of cremating the dead, Romani dead must be buried. Cremation and burial are both known from the time of the Rigveda, and both are widely practiced in Hinduism today (although the tendency for higher caste groups is to burn, while lower caste groups in South India tend to bury their dead). Some animals are also considered impure, for instance cats because they lick themselves.
Romanipen (also romanypen, romanipe, romanype, romanimos, romaimos, romaniya) is a complicated term of Romani philosophy that means totality of the Romani spirit, Romani culture, Romani Law, being a Romani, a set of Romani strains.
An ethnic Romani is considered to be a Gadjo (non-Romani) in the Romani society if he has no Romanipen. Sometimes a non-Romani may be considered to be a Romani if he has Romanipen, (usually that is an adopted child). As a concept, Romanipen has been the subject of interest to numerous academic observers. It has been hypothesized that it owes more to a framework of culture rather than simply an adherence to historically received rules.
