To deepen on the study of the concept of neologicity, an exhaustive review of the literature was carried out. Once the different parameters related to this concept were isolated, we realized that some of them were also used to determine the communicative function of neologisms. For this reason, first, we correlated the objective criteria to classify neologisms as prototypical of the denominative or the stylistic function with the parameters related to the neological quality. Second, we defined new criteria, both linguistic and chronological, to broaden the scope of our analysis. Afterwards, all the criteria were applied to a corpus of neologisms from newspaper articles and journalistic blogs in Spanish written by women and men. The results confirmed that neologisms with stylistic features tend to be more neological than denominative neologisms. Consequently, they are usually less frequent lexical units used in general or informal contexts. In addition, they tend to be the result of unproductive word formation rules that might contain subjective linguistic components and also tend to be more recent.
