In the [[nodal model]], a ''loop'' is a [[Wikipedia:Linked list#Circularly-linked list|circularly linked lists]] formed from nodal [[association]]s.

In the nodal model, a loop is a circularly linked lists formed from nodal associations. Since none of the nodes in a loop is a starting or finishing point, a loop can be referenced by any of its items. This means that a reference to a loop can also encapsulate the concept of an item of current focus, a concept used heavily by nodal reduction
