Scholars in various disciplines devote considerable attention to defining their terms. Consider the field of communication, for example. Dance and Larson (1976) reported well over 100 different definitions of the term “communication” in the literature. Much of the wrangling over what constitutes communication has centered on issues such as intentionality (Is communication necessarily intentional?), symbolicity (Is communication limited to symbolic action?), and the number of participants required (Does communication require two or more persons?).
