Quantifying the importance of morphomic structure, semantic values, and frequency of use in Romance stem alternations

Abstract Stem alternations in Romance have recently been argued to be regulated largely by autonomously morphological (aka morphomic) organizational principles. Here, I assess the relative contribution of morphomic structures vis à alternative principles, namely semantic structure, and token frequency. Results confirm exceptional importance domains on verb stem alternations; however, inherent inflectional values frequency also play a decisive role overall stem-morphological similarity different paradigm cells.
