Sui generis
In sociology, the "sui generis" is what has been externalized, then internalized in the overall public and becomes a part of society that simply exists in its construct. It is not something that is not thought to have been created, because it is imbedded in everyone's way of thinking and being. Instances include the idea of love, or going to school, or clothing belonging to a specific gender. These examples are "sui generis" for they simply exist in society and are widely accepted without thoughts of where they come from or how they were created.
Jus sanguinis
Jus sanguinis () is a principle of nationality law by which citizenship is not determined by place of birth but by having one or both parents who are citizens of the state. Children at birth may automatically be citizens if their parents have state citizenship or national identities of ethnic, cultural, or other origins. Citizenship can also apply to children whose parents belong to a diaspora and were not themselves citizens of the state conferring citizenship. This principle contrasts with "jus soli" (Latin: "right of soil").
