Resumen de Argumental comitative and reciprocity in Spanish
This research paper deals with the reciprocity relationships in Spanish. It is our intention to establish the conditions needed in reciprocal constructions and their distinctive characteristics. One of these features is the presence of an argument characterized by being semantically obligatory and syntactically marked by the Spanish preposition "con". This argument is referred to as 'argumental comitative' and is determined by a certain kind of symmetrical reciprocity, which is gradual and is related to the active role of the agent. This argument has to do with some types of alternations in Spanish verbs that present a syntactic constraint that is referred to as "complemento de regimen preposicional" in Spanish and is the syntactic function that represents the argumental comitative in these types of reciprocal constructions.
