The verbal constructions of ser y estar with adjectives in current Spanish are characterized by their complexity and unpredictability. For this reason, they have been the subject of multiple studies that have tried to discover the linguistic keys of the functioning of both verbs. Among the many questions raised by the use and function of ser y estar (both as autosemantic verbs and copulative nexus), the problem of the semantics of these verbs still stand out. This paper presents a study of ser and estar verbs in current Spanish with the aim of re-examining the nature of both verbs. We wil check if both verbs are just copulative nexus without any semantic value or, on the contrary, they are predicative verbs that present only existential and narrative values. This work defends the idea that both ser and estar are polyfunctional and polysemic verbs. In the case of estar, its clear polysemy is the key to understanding its uses as a predicative verb and also as a copulative nexus. In the case of ser, there are reasons to argue for and against polysemy in its uses as a nexual verb.
