Hittite h Initial = Indo-European bh

The relationship of Hittite and Indo-European has been recognized chiefly on the basis of certain correspondences in inflectional terminations, suffixes, and pronouns. Indo-European etymologies have, to be sure, been suggested for a considerable number of Hittite words, but a large proportion of these etymologies are clearly unsound and even those which are most plausible have never been worked into the sort of consistent system which could bring conviction to those who understand sound etymological method.
