Subject-clitic inversion and inflectional hierarchies

<jats:title>Abstract</jats:title><jats:p>This paper attributes the effects of subject-clitic inversion to a reversal of the normal hierarchy between Tense (T) and Mood (M) projections which is induced by certain modal or illocutionary features. The simple inversion pattern results from raising of the verb to M, while the subject raises to Spec TP. This structure provides a position (Spec MP) for the lexical subject in the case of complex inversion, without the need for multiple specifiers or additional functional categories. By raising to this position, the lexical subject binds a surrogate clitic in Spec TP, creating an argument Chain which contains a single theta-position and a single Case position. The implications of this analysis for subject questions and the phenomenon of stylistic inversion are also discussed in some detail.</jats:p>
