This paper presents, in a panchronic view, a description of the multifunctionality of the Brazilian Portuguese discourse markers olha e vê in a written and oral corpus from Santa Catarina State, Brazil. Based on a functionalist approach to grammaticalization, the analysis focuses on the semantic-pragmatic and categorical changes of those markers, and on the concepts of (inter)subjectivity and (inter)subjectification and their relation to the functions of language in the process of change. The analysis shows that (i) pragmatic polysemies emerge from communicative practices and signals, with different degrees, the interpersonal involvement between the speaker and the hearer, an increment of meanings related to the speaker's attitude towards what is said, and an incipient function of the markers on the textual dimension; (ii) the different discourse-function contexts of olha and vê are attested by frequencies of use that point to both variation and constraint contexts; (iii) there are clues to grammaticalization of those markers, in which olha seems to be in a more advanced process than vê.
