A morphism g is ambiguous with respect to a word u if there exists a second morphism h 6= g such that g(u) = h(u). Otherwise g is unambiguous with respect to u. Thus unambiguous morphisms are those for which the structure of the morphism is preserved... Read More about Unambiguous Injective Morphisms in Free Groups.
