The description of PIE phonology found in our handbooks date in great part from the nineteenth century. When we maintain these descriptions we accept the foundations on which they are based. At present our data have been increased by Hittite, and our linguistic methodology refined. In this monograph I shall examine the new data and some well-known but unexplained data in accordance with our current linguistic methodology and propose a revised description of PIE phonology.
