Monogamy: This is the practice of being married to only one person at a time. In many modern societies, this takes the form of Serial Monogamy, where individuals have a sequence of exclusive partners through divorce and remarriage.
Polygyny: A form of polygamy where one man is married to several women simultaneously. This is historically common in societies where wealth is measured by the size of the labor force or the number of offspring.
Polyandry: A rarer form of polygamy where one woman is married to several men. Fraternal Polyandry, where a woman marries a group of brothers, is the most documented variation, often used to keep family land intact.
Group Marriage: An arrangement where multiple men and multiple women form a single family unit. This form is extremely rare and usually exists as a temporary or experimental social structure.
| Rule Type | Definition | Social Function |
|---|---|---|
| Endogamy | Marriage within a specific social, ethnic, or religious group. | Preserves group identity and keeps resources within the community. |
| Exogamy | Marriage outside of one's own social or kinship group. | Builds external alliances and prevents genetic inbreeding. |
| Hypergamy | Marrying a person of higher social status or caste. | Provides a path for upward social mobility, often for women. |
| Hypogamy | Marrying a person of lower social status. | Often socially discouraged as it may lead to a loss of status for the higher-status partner. |
Terminology Precision: Always distinguish between 'Polygamy' (the general term for multiple spouses) and its specific forms, 'Polygyny' (multiple wives) and 'Polyandry' (multiple husbands). Using the general term when a specific one is required is a common point-loss area.
Functional Analysis: When asked why a specific marriage form exists, look for the environmental or economic 'trigger.' For example, link Polyandry to land scarcity and Polygyny to agricultural labor needs.
Identify the 'Serial' Prefix: In modern contexts, 'Monogamy' is rarely lifelong. If a question describes a pattern of multiple marriages over a lifetime but only one at a time, the correct technical term is Serial Monogamy.
Check Selection Rules: Be prepared to identify whether a scenario describes Endogamy (internal) or Exogamy (external) based on the boundaries defined in the prompt (e.g., village, religion, or family).
The 'Rarity' Misconception: Students often assume polyandry is non-existent because it is rare in Western culture. In reality, it is a stable and logical system in specific high-altitude or resource-poor regions.
Confusing Levirate with Polygyny: While Levirate involves a man having multiple wives (if he is already married), its primary purpose is social security and lineage maintenance for the deceased, not just the expansion of the husband's household.
Equating Marriage with Romance: In a sociological context, marriage is analyzed as a structural and economic contract. Avoid using 'love' as the primary explanation for marriage forms in academic responses unless the question specifically addresses affective bonds.
