The quality of redundancy in language usage can be examined to determine its effect on communication efficiency. Semiotic redundancy, defined as the quantity of prolixity between semantic and pragmatic information, has the potential of reducing equivocation and error and, at the optimal level, provides maximum communication efficiency. Thus, redundancy in communication interchanges, when joined with redundancy in the human memory, holds the key to information transfer between people. Research into the semantics, syntactics, and pragmatics of information interchange yields the optimum level of redundancy for truly efficient communication. (CH)
