International audience; This paper contributes to addressing the Paradigm Cell Filling Problem (PCFP) in inflectional paradigms, as defined by Ackerman et al. (2009). We define a method for extending the use of conditional entropy to address the PCFP to prediction based on multiple paradigm cells. We apply this method to French and European Portugese and show that, on average, knowledge of multiple paradigm cells is dramatically more predictive than knowledge of a single cell. Moreover, this new entropy measure proves useful in studying principal parts systems, which correspond to sets of predictors yielding a null entropy. Using a graded measure allows us to highlight the relevance of non-categorical or “good enough” principal parts systems.

Suppletion manifests itself when some of forms of a word are based on different stems, such as the opposition between I go/I went in English. In morphology, suppletion has two related meanings: (i) suppletion is a diachronic process by which two words mix their forms to give rise to a single word with a paradigm with suppletive alternation; (ii) suppletion is the most extreme case of morphological irregularity, where stems used in the same paradigm are synchronically unrelated, independently of etymology. In both senses, suppletion is a property of paradigms and as such mostly related to inflectional morphology.
