Write in detail about Iravati Karve's comparative analysis of kinship system in four cultural zones of India.

1. Northern Zone

• Linguistic base: Indo-Aryan languages.
• Kinship pattern: It is governed by the rule of village exogamy and gotra exogamy.
• There is a strict avoidance rule between affinal relations.
• No marriage between cross-cousins is allowed.
• The system focuses on maintaining distance between lineages.

2. Southern Zone

• Linguistic base: Dravidian languages.
• Kinship pattern: Shows a strong preference for cross-cousin marriage (MBD - Mother's Brother's Daughter; FSD - Father's Sister's Daughter).
• Marriage is a mechanism to consolidate property and strengthen affinal ties.
• The distinction between parallel and cross-cousins is central to the terminology.

3. Central Zone

• Linguistic base: A mix of Indo-Aryan and Dravidian influences, often referred to as a 'transition zone'.
• Kinship pattern: Displays features of both North and South.
• In some tribes and groups, cross-cousin marriage is permitted, but it does not have the same structural rigidity as in the South.

4. Eastern Zone

• Linguistic base: Austro-Asiatic and Tibeto-Burman languages.
• Kinship pattern: Highly varied, reflecting the diverse tribal populations.
• Many groups exhibit matrilineal systems (e.g., Khasi, Garo) where lineage is traced through the mother, and residence is often matrilocal.

Significance of her work:

• Karve moved away from viewing India as a monolithic society.
• She highlighted how language, culture, and social organisation are intertwined.
• Her work remains a foundational text for understanding the regional variations of Indian social structure.
