Fixed expressions comprise a large, specific and diverse group of linguistic units which makes them a serious theoretical and lexicographical challenge. This article offers a review of the existing classifications. There is also a new model proposed – one which distinguishes between a core and a periphery. Manifestations of structural variability are also considered in two directions: in language and in speech. The observations are based on the corpus in one of the Bulgarian phraseological dictionaries.
