for logic variable
From The Free On-line Dictionary of Computing (30 December 2018) :
A variable in a logic programming language
which is initially undefined ("unbound") but may get bound to
a value or another logic variable during unification of the
containing clause with the current goal. The value to which
it is bound may contain other variables which may themselves
be bound or unbound.
For example, when unifying the clause
sad(X) :- computer(X, ibmpc).
with the goal
the variable X will become bound to the atom "billgates"
yielding the new subgoal "computer(billgates, ibmpc)".
