Abstract

The objective of this paper is to analyse the incidence of medical discourse in the functioning of the periphrases associated with the grammatical aspect. To this end, we examine the treatment of the aspectual formations in specialized texts, specifically in the field of medicine. Based on the hypothesis that the communicative situation influences the behaviour of the category object of study, we carry out a comparative analysis of the aspectual periphrases used in general communication and in specialized discourse by means of two fundamental variables, namely: frequency of use and semantic values. As we show, the grammatical category modifies its distinctive properties from one discourse to another.
