Summary : A consistent theoretical description of the many anomalous properties that characterize the pseudogap phase in the underdoped region of the cuprate phase diagram has proved challenging. The consistent progress in spectroscopic and other experiments suggests a phenomenological approach. An ansatz based on analogies to the transition to Mott localization at weak coupling in lower dimensional systems, has been proposed by Yang, Rice and Zhang*. This ansatz has had success in describing a wide range of experiments**. The motivation underlying this ansatz is described and some comparisons to experiment are reviewed. Implications for a more microscopic theory are discussed together with the relation to theories that start directly from microscopic strongly coupled Hamiltonians.
