Title: A gramaticalização do item "fora" no Português do Brasil: a unidirecionalidade do processo
Abstract: In a theoretical functionalist framework, which prioritizes the study of the language in constant change from its use (HALLIDAY, 1978), it is analyzed the grammatical and semantic alterations on a lexical item that suffers grammaticalization in the Portuguese from Brazil.The most general objective is to evaluate the existing difference among the models of analyses considered by Lehmann (1982), Hopper (1991), Heine, Claudi and Hünnemeyer (1991) and Castilho (2006), when applied the data of the spoken and written modalities.The chosen item to proceed the study is the adverbial item-source FORA (out), that discloses a unidirectional passage in the grammaticalization process.It is evident that to this unidirection implies to a route of sufficiently intense functional abstraction that culminates with its recategorization in the grammatical item.
