Phraseology is located at the intersection of lexicon and syntax. It deals with polylexical signs composed of, at least, two words (even a single one, if its use is idiomatic) which are fixed, repeated and often figurative. Polylexicality, (gradual) frozenness, repetition and institutionalization are, in fact, the essential properties that characterize the PU and that allow them to be distinguished from free productions.


History of the phraseology

The father of Phraseology is Charles Bally, with his work Traité de Stylistique Française (1909). He was the first to give name to this field and to make a systematic classification of the elements of the fixed combinatorial language. Others have previously been able to refer to this linguistic phenomenon (see Michel Bréal), but it was Bally's work that drove the development of this discipline, nowadays became a linguistic discipline.


Theoretical phraseology

The object of study of Phraseology are the phraseological units (PU) of the language. This field analyze the formal, semantic and pragmatic properties of these elements and classify them into categories. Based on empirical studies, phraseology identifies the theoretical principles that describe how PU work in discourse.


Applied phraseology

Applied phraseology covers practical areas such as Phraseodidactics, Phraseotranslatology and Phraseography, among others. In order to develop their own fields of application, these are based on the principles set by theoretical phraseology.
