A Lierne (from the French lier - to bind) in Gothic rib vaulting is an architectural term for a tertiary rib spanning between two other ribs, instead of from a springer, or to the central boss. The type of vault that utilizes liernes is called a lierne vault or stellar vault (named after the star shape generated by connecting liernes).
