----One of the many problems in Tocharian historical phonology is the development of labiovelars. Though progress has been made in recent years the exact history of the PIE labiovelars and sequences of palatal/velar plus *u/*w in Tocharian has still to be written. The interesting fact that in the Tocharian script two reflexes of the Proto-Tocharian labiovelar in Tocharian B, namely <kw> and <ku>, compared to only one in Tocharian A, i.e., <ku>, has further complicated the picture. In this study it is argued that the two reflexes of the Proto-Tocharian labiovelar in Tocharian B can be explained as the interference of different phonostyles.
The Syntax and Semantics of Agent Formations in Tocharian (2017), by Hannes A. Fellner, In: Verbal Adjectives and Participles in Indo-European Languages. Proceedings of the conference of the Society for Indo-European Studies (Indogermanische Gesellschaft), Paris, 24th to 26th September 2014.

Tocharian employs a number of semantically and morphologically related agent formations in B -a and A -ø (formations in B-tsa A-ts, B-ntsa, A-nt, B-nta A-nt, the nt-participle B -ñca A -nt, formations in B -uca, and verbal governing compounds in B -a A -ø) that all inflect in the same way. While there have been different proposals about the PIE origin of these formations, the synchronic patterning of these formations in Tocharian has largely been outside the focus of recent studies. This paper focuses on the syntax and semantics of the agent formations in Tocharian B -a and A -ø. It shows that the a-cross-the-board categorization of this morphological category as agent nouns sensu stricto in the newer literature is not warranted and that the majority of these agent formations are participial based on the criteria auf case assignment, attributive use and modification by adverbs.
