  • church-rosser theorem — (theory)   A property of a reduction system that states that if an expression can be reduced by zero or more reduction steps to either expression M or expression N then there exists some other expression to which both M and N can be reduced.

It does not imply that a normal form is reachable, only that if reduction terminates it will reach a unique normal form.
