Original h in Hittite and the Medio-Passive in r

I have tried to show (L anguage 3. 109–22) that Hittite h occurs where the Indo-European languages have bh initial, and I can now make two or three additions to the material there presented. In L anguage 4. 122 f. I have connected halanta ‘head’ with Greek φαλός·λευκός, φαλακρός ‘bald’, and Sanskrit bhālam ‘forehead’, on the assumption that the original meaning of the Hittite word was ‘bald’. Hittite haš-, hašh - ‘open’, must be identified with IE *bhosos ‘naked’, whence Lithuanian bãsas ‘bare-foot’, Old English bær , etc. The verb pihiš -, which, accompanied by the adverb arha , means ‘strike off, cut off, take off’ or the like, contains the verbal prefix pe -, while hiš - is an extension in s of the root which appears in IE *bhei - ‘strike’ (Old High German bīhal ‘axe’, etc.), and whose extended form *bheid - means ‘split’ (Sanskrit bhinadmi , Latin findo , etc). Another instance of h = bh after the verbal prefix pe - is pehar(k) - ‘hold towards’ ( Keilschrifttexte aus Boghazköi 4. 2. 2. 25, Keilschrift-Urkunden aus Boghazköi 13. 4. 4. 37) beside har ( k )- ‘have’ on which see L anguage 3. 117 f.
