Corrigendum

On pg. 235 in discussing the origin of the a-stem dative singular I write "PIE *-eh2iC ought to give -āi and *-eh2iV ought to give *-ai"  Of course, the conditioning environments are reversed.  In preconsonantal position the i would be syllabic and the h2 intervocalically would have been lost.  In prevocalic position the i would be nonsyllabic and the h2 would be lost in the coda with compensatory lengthening.
