Gregory Stump

Ph.D. in Linguistics, The Ohio State University, 1981
M.A. in Linguistics, The Ohio State University, 1978
B.A. in French, University of Kansas, 1976

In recent years, my research has focused on the theory and typology of inflectional morphology:

  • In a series of publications, I have argued for an inferential-realizational theory of inflectional morphology known as Paradigm Function Morphology.  Most recently I have been investigating the role of inflectional paradigms as a grammatical interface and the algebra of morphotactics.
  • Together with Raphael Finkel, I have argued for a novel approach to morphological typology based on the implicative patterns in a language's inflectional paradigms.

From 2006 through 2020, I served as co-editor of the journal Word Structure (Edinburgh University Press).

In 2017, I was inducted as a Fellow of the Linguistic Society of America:
