This study has two aims. First, it introduces an under-studied construction in Hijazi Arabic (HA) and investigates its intonational, semantic, pragmatic, syntactic, and information structure properties. This construction is termed as focus preposing. It is a non-canonical syntactic option used to express a speciﬁc aspect of information structure such as contrastive focus (e.g., Moutaouakil, 1989). Second, it aims to investigate whether a focus preposing in HA is associated with a particular intonational tune. To fullﬁll this aim, 480 declaratives were constructed. These sentences were elicited from sixteen native speakers of Hijazi Arabic. These sentences were embedded in questionanswered paradigms to evoke contrastive focus on the preposed item realized at the left periphery of the HA clause. The intonational structure of this construction shows to have a nuclear pitch accent [L+H*] placed on the stressed syllable of left-realized word, followed by post-focus compression till the end of the structure. This ﬁnding provides evidence for Liberman & Sag; Marandin’s (1974; 2006) claim that the tune determines the meanings.
