The No-Meaning Falsity: The Structural Impossibility of the Arbitrary Sign in Classical Arabic
Summary
This paper mathematically models Classical Arabic morphology to argue against Saussurean arbitrary sign and postmodern semantic indeterminacy, proving that Arabic lexical meaning is structurally determined via root-pattern pairs and showing a complexity asymmetry over Indo-European languages.

# The No-Meaning Falsity: The Structural Impossibility of the Arbitrary Sign in Classical Arabic Source: [https://arxiv.org/abs/2608.07737](https://arxiv.org/abs/2608.07737) [View PDF](https://arxiv.org/pdf/2608.07737) > Abstract:This paper investigates whether the postmodern claim of unrestricted semantic indeterminacy, and its foundational Saussurean axiom of the arbitrary sign, are compatible with the structural architecture of Classical Arabic\. We develop a formal mathematical model of Arabic non concatenative morphology in which lexical meaning is determined by the interaction between an invariant root and a morphosyntactic pattern\. Within this framework, we establish a Morphological Correspondence Theorem, demonstrating that every lexical item is uniquely generated by a root pattern pair, and a Semantic Localization Theorem, proving that lexical meaning is determined at the derivational level prior to surface realization\. To address Saussurean weaker notion of relative arbitrariness, we formalize it via conditional Kolmogorov complexity, defining arbitrariness algorithmically as the no rule property\. We prove that general relative arbitrariness is formally undecidable, while Arabic relative arbitrariness is decidable and provably less than 1 for its motivated signifiers \(Levels W and M\), establishing a strict system complexity asymmetry over Indo\-European languages\. ## Submission history From: Elnaser Abdelwahab \[[view email](https://arxiv.org/show-email/d5c0192c/2608.07737)\] **\[v1\]**Fri, 7 Aug 2026 20:01:20 UTC \(38 KB\)

The JEPA Paradox in Language: The Geometry of Linguistic Alternatives
This paper analyzes why deterministic JEPA-style latent prediction works for images but not for text, attributing the failure to high conditional variance in language where masked contexts admit multiple valid completions whose representations lack a coherent center.
Determinization in Structure Theories: A Unified Framework via Closure, Comparability, and Joint Admissibility
This paper presents a formal framework for constructing canonical interpretations from plural structure theories, motivated by structural failures in LLM-assisted reasoning. It distinguishes types of non-determinism and provides conditions for licensed canonicalization, without establishing full determinization for all cases.
When Similar Means Different: Evaluating LLMs on Arabic--Hebrew Cognates
This paper introduces SemCog Bench, a curated benchmark of 1,858 Arabic-Hebrew word pairs with sentence-level annotations, to evaluate LLMs' ability to distinguish true cognates from false friends and loanwords. Results show high accuracy on true cognates but sharp drops on false friends, highlighting a key limitation in cross-lingual semantic reasoning.
