This thesis explores the flexible word order of Jakarta Indonesian (JI), a variety of spoken Indonesian used in the capital Jakarta area, but also widely used in the Indonesian media. JI is largely an SVO language, but this research sets out to describe non-canonical object positions outside of the base generated SVO order. Two non-canonical object positions are of special interest: (i) the sentence-initial object position that frequently alternates with the SVO order; and (ii) the medial object position within the vP projection that requires movement of the verb to accompany this phase-bound short object movement. In this thesis, I show that non-passive object-initial constructions share many similarities with characteristics of Scrambling, especially as described for Japanese Scrambling, namely: (i) mixed A/A’ properties (Mahajan 1990, 1994); (ii) sensitivity to islands (Saito 1985); and (iii) introduction of scope ambiguity (Kuno 1973, Hoji 1985, Hayashishita 2000). The medial object position that requires short object movement within the vP is interesting because this movement must be followed by verb movement (unlike Scrambling that can apply freely); this is similar to what has been described for Object Shift in Germanic languages (Holmberg 1986). Thus, this work is significant in showing that the contrast whereby long-distance object movement that crosses a phase boundary (Scrambling) does not require verb movement, while short distance object movement within a phase (Object Shift) does, can exist within the grammar of one language. This lends support to the proposal that the verb movement requirement on short object movement is a result of shape preservation where the VO base generated order must be maintained. Crucially though, this linearization rule must apply cyclically by phase to explain why Scrambling does not have to follow this requirement (Fox & Pesetsky 2005, Müller 2007).
