What is theory?

Sholars and theorists have defined theories in varied ways and every different definition implies how theory can do wonders for us. Theories have been defined as “set of interrelated propositions” (Hoover, 1984), “set of systematic hunches” (Burgoon, 2012) “set of systematic generalization” (Severin & Tankard Jnr., 1982) “set of ideas” (McQuial, 1983).
