🔡 Root

Greek endon = within; gamos = marriage; coined 1865 by John Ferguson McLennan

📜 Etymology

From Greek endon ("within") + gamos ("marriage"); coined in 1865 by Scottish social anthropologist John Ferguson McLennan.

🧠 Memory Hook

ENDO- = "within" (as in endoscopy, looking within) + -GAMY = "marriage" (as in monogamy); so endogamy is marrying within your own group.

🎯 How This Word Works in UPSC Writing

The rule requiring marriage within one's own group. Its sociological significance is that it is the mechanism by which caste reproduces itself, since a system of hereditary ranked groups can persist only if group membership is closed, and closing it requires controlling marriage. That is why Ambedkar identified endogamy as the essence of caste rather than as one of its features, arguing that caste is fundamentally an enclosed class and that the practices surrounding women's marriage exist to maintain the enclosure. Two consequences follow that are directly examinable. Caste survives urbanisation and occupational change because those alter what people do without altering whom they marry, which is why matrimonial advertisement remains caste-organised even among the highly educated. And endogamy has a biological consequence too, since strong founder effects within closed groups raise the frequency of certain recessive disorders, so the social rule has become a public health question.

⚖️ Don’t Confuse It With

Endogamy requires marriage within the group and exogamy marriage outside a specified group, and Indian practice usually combines them, since one marries within the caste but outside the gotra or village. Hypergamy, or anuloma, is marriage of a woman into a higher group, and hypogamy or pratiloma the reverse, traditionally disapproved. Sanskritisation is the adoption of upper-caste practices to claim higher status, which works within the system rather than against it, whereas inter-caste marriage challenges the system directly.

What is the difference between endogamy and exogamy?
Endogamy requires marrying within a specified group and exogamy outside one; Indian practice typically combines both, marrying within the caste but outside the gotra.
