|Abstract:||Bulgarian lexical accent has been analyzed in the frame of prosody-morphology interface and the Head dominance theory of Revithiadou (Revithiadou 1999). The theory suggests that the accent characteristic of the morphological head determines the accent pattern of the lexical unit. The principle of headedness solves the conflicts between the accent specifications of morphemes. The analysis of Bulgarian lexicon proves that claim. For example the accented derivational suffix -áč associates with verb's root gótv- (gótvja 'to cook'), composing a nomina agentis noun gotváč 'cook'. The accented head morpheme -áč deletes the prosodic characteristic of the originally accented root and determines the accentual pattern of the derivative. If both root and inflectional suffix are not marked, as in stádo 'herd', a default trochaic foot surfaces.
