Drawing Parallels Between Language Change Processes: Grammaticalization, Constructionalization and Phraseologization

Over the last decades, the acknowledgment of the dynamic character of language has led to the focus on language evolution and change. Among the different streams of linguistics, Historical linguistics (morphosyntax), Construction Grammar and Phraseology have paid attention to these processes, studying grammaticalization, constructionalization and phraseologization, respectively. The three frameworks we are dealing with were quite different in origin, but through the adoption of cognitive, usage-based, pragmatic approaches they are tending to converge. In this paper we will outline the respective frameworks, their conception of language unit and the process of change, including its mechanisms and stages. In each section, we will include some applications in Catalan language. As we consider them to be complementary, since they account for different items of language, at the end we will suggest an integration of the three of them.
