Ficar, tornar-se e virar em construções relacionais: variação e/ou mudança construcional?

Based on constructionist approach of Goldberg (1995, 2003, 2013) and Traugott & Trousdale (2013), this research focuses on the relational construction of state change and the variation/alternation between the verbs ficar, tornar-se e virar (stay, become and turn) in this type of construction in Brazilian Portuguese. The verbal forms that alternate are investigated in the same context (predicative construction of a change of state) and motivations for the variation to occur. The main objective of this research is to identify: (i) constructional verbal patterns of change of state in Brazilian Portuguese based on frequency and in the relations of form and/or meaning by family similarities existing in the instances of use of such verbal forms; (ii) the configuration of the relational construction of state change (in view of state construction formulated in Goldberg, 1995); (iii) the functional differences between the microconstructions with ficar, tornar-se e virar, seeking to analyze how the variation/alternation between such verbs occurs in the construction of change of state. The data were collected in academic articles, journalistic texts and texts accessed in some sites of evaluation or complaint and analyzed according to some parameters, among which: (a) the type of subject and of predicative syntagma; (b) the more permanent/more transient aspect of the construction; (c) the degree of formality of the context in which it was recorded. This paper also evidences the central place of variation in Construction Grammar.
