In Meaningful Games, Robin Clark explains in an accessible manner the usefulness of game theory in thinking about a wide range of issues in linguistics. Clark argues that we use grammar strategically to signal our intended meanings: our choices as speaker are conditioned by what choices the hearer will make interpreting what we say. Game theory--according to which the outcome of a decision depends on the choices of others--provides a formal system that allows us to develop theories about the kind of decision making that is crucial to understanding linguistic behavior.
