− | Each object stored in a linked list is known as an '''element''' or '''value'''. The address of the next value is known as a '''link''', as it "links" the element to the next one. A value and the corresponding link, stored together and taken collectively, are known as a '''node''' of the list. The '''size''' or '''length''' of a linked list is the number of elements or nodes it contains. A list may be empty if it contains no elements. If it is not empty, its first node is known as the '''head''', and the rest of its elements, which themselves form a linked list, are known as the '''tail'''. There are traditionally two functions on a linked list: one that returns the head, known as '''car''', and one that returns the tail, known as '''cdr | + | Each object stored in a linked list is known as an '''element''' or '''value'''.
