We define a class of erased-word processes and prove that the polyadic filtration generated by such a process is standard. This is shown by firstly constructing a generating process of innovations in the case of a finite alphabet equipped with the uniform probability measure, and then by deriving the general case with the help of the tools of Vershik’s theory of filtrations in discrete negative time.
