Description:
<jats:title>Abstract</jats:title><jats:p>This article studies the various suppletive patterns found with respect to the Romance movement verb <jats:sc>go</jats:sc>, both under a diachronic and a synchronic perspective, within the framework of <jats:italic>Distributed Morphology</jats:italic> (DM). The Romance varieties all started with the loss of verbal forms of Lat. <jats:italic>īre</jats:italic> – indeed, there is no Romance variety that retained the full paradigm – but reached different solutions in diachrony. A particular case, implemented by underspecified <jats:italic>Vocabulary Items</jats:italic> in DM, is overlapping suppletion, as found in Spanish, where the absolute default auxiliary <jats:sc>be</jats:sc> shares part of its forms with <jats:sc>go</jats:sc>. In this article, different types of suppletion are distinguished and selected aspects of suppletion are analysed in order to illustrate how DM can systematically account for them. From the perspective of DM, we discuss why non‐categorial suppletion is restricted to the present tense, how resistance to innovation of 1/2pl can be modelled and how subsequent analogical levelling can be formalised. Finally, we show why, as in Ibero‐Romance, forms of <jats:sc>be</jats:sc> can be used for <jats:sc>go</jats:sc>.</jats:p>
