The present paper investigates the Hijazi Arabic (HA) morphosyntactic properties of the widely known linguistic phenomenon of sluicing from a generative perspective, taking into account the latest advancements of the Minimalist Approach (Chomsky 1995, 2000, 2001). In this paper, sluicing is a linguistic phenomenon of deleting an entire TP clause, leaving only a wh-remnant. Adopting the Structural PF-Deletion approach, we argue that HA employs sluicing and that the ellipsis site contains a fully-fledged syntactic structure that must be deleted at the PF level after the movement of the remnant to a higher CP. On a par with previous crosslinguistic ellipsis studies, the current study shows that ellipsis is permitted if and only if there is a specific head carrying some specific morphosyntactic properties occurring in a local relation to the ellipsis site. This specific head, with its morphosyntactic properties, licenses for the ellipsis phenomenon to occur. The head properties trigger the whword to move from its base-generated position to the specifier position of this particular head, i.e., Spec CP, and then delete all other constituents included within the TP.

This paper focuses on the obligatory movement operations that Najdi Arabic (NA) verb forms must undergo to satisfy the morphosyntactic requirements within the minimalist program (MP). Recall that the practice of the MP syntactic theory, including its further advancements, proposed by Chomsky (1995, 2000, 2001) springs from the fact that the grammar of a language starts basically from the lexicon from which suitable words are selected to form clauses. The selected words undergo some syntactic operations such as Merge, by which larger constituents are formed, and Move, by which the formed constituents move to higher positions in the hierarchy to fulfil some specific syntactic purposes. When the elements have undergone the operations of Merge and Move they are spelled out into phonetic forms (PF) and logical forms (LF). In light of this, we argue that NA verbs start out as roots in the head of VP before merging with the vocalic affixes in the head of Tax-AspP to satisfy the subjectverb agreement requirements and mark the aspect features. Perfective verb forms must then continue to move to T to merge with the past tense abstract features while imperfective forms stay in Tax-AspP. The thematic subject is generated in Spec,VP; it may stay there to derive the VSO order, or move higher to derive the SVO order. The findings show that obligatory movements indicate interactions between the functional categories of TP, Tax-AspP and VP: NA verbal roots obligatorily move to Tax-Asp to derive (im)perfective forms; perfectives obligatorily move to T.

Both Classical Arabic (CA) and Modern Standard Arabic (MSA) use the six negative particles: laa, maa, laysa, lam, lamma, and lan. Other Arabic varieties have only two negative particles. For instance, Hijazi Arabic (HA) uses laa and maa. This shows that the three varieties (CA, MSA, and HA) have the same underlying negatives, namely, laa and maa, but CA and MSA have a number of inflected forms of laa that HA does not have. The paper shows how HA uses the two negatives when scoping over verbal clauses while the other two varieties, i.e., CA and MSA, use all the six negatives. It is worthy of note here that HA is descendant from CA which has the six negatives. This suggests that HA must have lost the inflected variants of laa..
