This article presents an analysis of some phraseological units, conversational routines, according to their independence degree, in order to restructure Sphere III (Corpas, 1996). In this Sphere there are also proverbs and idioms. In an attempt to classify Spanish phraseological units, we have taken as a model the system proposed by Briz and Val.Es.Co. Group (Briz & Grupo Val.Es.Co., 2003, 2014) for conversational segmentation. This system characterizes some statements in terms of different degrees and types of independence, which allow us to restructure Sphere III. This paper adopts a phraseological and pragmatic approach, with examples taken from Corpus de conversaciones coloquiales (Briz & Grupo Val.Es.Co., 2002).
