The claim that ambisyllabicity applies universally to all words across human languages is false, as languages exhibit diverse syllable structures, strict phonological boundaries, and language-specific constraints.
The claim is specific and empirical, thus passing Step 0. However, none of the retrieved papers support the claim of universal ambisyllabicity; instead, multiple cross-linguistic studies demonstrate that languages employ distinct syllabic constraints, phonological word boundaries, and hierarchical organizations that vary widely and contradict the notion of universal ambisyllabicity.
