The main topic of this paper is to outline the distinctive features of Spoken Bulgarian. One of the fundamental syntactic characteristics of spoken language is discussed: doubling of arguments. Observations are focused on syntactic variations for initial repetitions of words and phrases in spontaneous spoken language. Structural and discourse-oriented analyses are applied to show the mechanisms used by the speakers in communicative interaction and to identify the cases of syntactic variations. Repetitions may signal initial commitment of the speaker, hiatus, resumption or restart of speech.
Key words: syntax, doubling, communicative strategy, Spoken Bulgarian.
