An idempotent phonological grammar maps phonotactically licit forms faithfully to themselves. This paper establishes sufficient conditions for idempotency in Optimality Theory. Building on Tesar (2013), these conditions are derived through two steps. First, idempotency is shown to follow from a general condition on the faithfulness constraints. Second, this condition is investigated for a variety of faithfulness constraints within McCarthy and Prince's (1995) Correspondence Theory. This formal analysis systematizes a variety of approaches to chain shifts within classical OT.
