The termination of a confluent one-rule string-rewriting system R = (s + I} is reduced to that of another one-rule system K = {s' -B t') such that s' is self-overlap-free &of). A necessary and sufficient condition is given for termination of a one-rule system R = {s --+ t} such that s is sof and s o
