Practicing endogamy; tending to marry or reproduce only with members of one's own social group, community, or family.
From Greek 'endo-' (within) and 'gam-' (marriage) plus the adjective suffix '-ous.' Describes individuals, groups, or populations with inbreeding patterns.
Royal families in Europe were famously endogamous to keep 'pure bloodlines,' which ironically led to genetic problems like hemophilia spreading through royal lines!
