cadr (plural cadrs)

  1. (computing) Car of the cdr in LISP. The second element in a list.
    • Matt Kaufmann, Panagiotis Manolios, and J Strother Moore, Computer-aided reasoning: an approach, 2000 :
      If we let x denote the tree (1 2 3), then the car of x is 1, the cdr of x is (2 3), the cadr of x is 2, the caddr of x is 3, and the cdddr of x is nil.
