Latin -rier and its Indo-Iranian congeners.

A largely overlooked equation of the Latin present passive morpheme -rier with Sabellic [fẹ:(r)] (Osc. - fír, U. -f(e)i) and further Indo-Iranian * -dhi̭āi is discussed and defended, with new argumentation and hitherto unappreciated or ignored philological material. The history of the Indo-Iranian infinitive ending is examined afresh and reevaluated, also on the basis of much hitherto unappreciated philological material: contrary to the prevailing view, it was originally depresential rather than deradical, and probably used with derived thematic verbs. This has important ramifications for Indo-European and for the distribution of Latin -rier. [ABSTRACT FROM AUTHOR]
