This article aims to advocate for the incorporation of event relations as a source for studies in historical linguistics, specifically, in research on lexicon. For this, the consolidated relationship between the history of the language and the history of the literary language is reviewed, a link that is particularly observed in the Spanish of the Golden Age, as well as the persistence of this trend in the diachronic corpus of the Royal Spanish Academy (CORDE and CDH), where the number of event relationships is limited. It also highlights some of the problems associated with the bibliographic information and the edition of the relations of events present in these corpus and, in addition, it is illustrated how these texts can fill the gaps in documentation about the foreign voices introduced in the Spanish language. Finally, some considerations are made to achieve a common digital model useful not only for historians of the language, but also for specialists from other disciplines.
