Früh-, Mittel-, Spätindogermanisch. Akten der IX. Fachtagung der Indogermanischen Gesellschaft (Zürich, 5.–9. Oktober 1992). — Ed. by G. E. Dunkel, G. Meyer, S. Scarlata and Chr. Seidl. — Wiesbaden: L. Reichert Verlag, 1994. — P. 1-15.This paper examines the question whether suffixal derivatives made from thematic stems may show the thematic vowel in the e-timbre (as is usually supposed for the IE "collective" in *-eh₂) and comes to a negative conclusion.
