In this paper I take a look at a classic problem in Spanish morphosyntax, namely the alternation between the forms -se and -ra in the Imperfect Subjunctive (Imperfecto de Subjuntivo). Research on this topic has mainly focused on sociolinguistic variation, and has been done almost exclusively with impressionistic data and speakers’ intuitions. I address the problem from a usage-based perspective, using corpus linguistics methods. The main claim is that the choice between -se and -ra correlates to a certain extent with morphosyntactic and discourse factors. Through collostructional analysis I also show that there exists repelled and attracted collexemes that distinguish and relate both forms.

西班牙语虚拟语中的世俗交替

在本文中，我研究了西班牙形态语法的一个经典问题，即不完美虚拟语（Imperfecto de Subjuntivo）中-se和-ra形式的交替。关于这个话题的研究主要集中在社会语言变异上，并且几乎完全是用印象派数据和说话者的直觉来完成的。我使用语料库语言学方法从基于用法的角度解决了这个问题。主要主张是-se和-ra之间的选择在一定程度上与句法和话语因素相关。通过共同的分析，我还表明存在排斥和吸引的个体，它们区分并关联了这两种形式。
