What is the meaning of Jvs sanguinis?

"Jus sanguinis" is a Latin term meaning "right of blood." It refers to a legal principle by which a person's nationality or citizenship is determined by the nationality of their parents rather than by their place of birth. This principle contrasts with "jus soli," which grants citizenship based on the location of birth. Countries that follow jus sanguinis often require that at least one parent be a citizen for their child to acquire citizenship.
