Peter Hallman was a keynote speaker at the Workshop on Deadjectival Verb Formation in Indo-European, held on 10 and 11 March 2023 in Vienna at the Austrian Academy of Sciences's Institute of Iranian Studies.
The keynote talk, "A>V in the English Passive Participles", discusses the English passive participle morpheme as a case of historical adjective-to-verb derivation by virtue of loss of function of the original adjectivizing morphology.
