Verbal suppletion: an analysis of Italian, French, and Spanish to go

In this paper, the A. attempt to show that person-number suppletive replacements follow language-specific alternation patterns, or templates, which mark the positions of stem alternations often shared by several verbs. These paradigmatic frameworks are stored in the lexicon with their verb forms and guide verbal restructuring processes by serving as the base configuration for suppletive replacements. The relative strength of a pattern is directly related to the number of verbs associated with it such that the most productive template is represented by completely rule-driven patterns, the template of lowest productivity encompasses only one verb, and all intermediate stages of productivity are represented by templates shared by various numbers of verbs
