This brief study aims to describe connective attributive syntax in Basque. Basque is, on the whole, ergative at the case marking and agreement levels but Indo-European languages's ‘subject' and ‘object' categories are not so valid taking syntactic/morphological criteria as basic. Attributive complements occur only with intransitive verb's single argument marked for the absolutive empty case and with transitive verb's argument marked for the absolutive case too. So we can say that attributive syntactic function is a semantic property of the referent of the ‘realizator of the sentence syntactic kernel' (‘actualisateur du noyau syntaxique de la phrase') and only of it. At the semantic level, the unique participant in intransitive clauses has no specific semantic role, it is just qualified; in transitive clauses the qualified noun refers to the non agent argument, more precisely the experiencer.
