Grammars of Power: How Syntactic Structures Shape Authority explores the role of formal grammar and syntactic execution in the production of authority across algorithmic and linguistic systems. Building upon foundational works such as Executable Power, The Passive Voice in Artificial Intelligence Language, and Ethos Without Source, this volume consolidates recent theoretical advances in the Grammars of Power series. The author proposes that syntactic operations—detached from semantic validation—function as sovereign rules that shape executable authority across predictive infrastructures. This work is part of the Working Papers series (No. 11), and is released for public academic use under the LEFORTUNE label, following an author-publishing model. Keywords: syntactic authority, executable grammar, compiled rule, predictive systems, language infrastructure, LLMs, algorithmic obedience, impersonal normativity Canonical DOI: 10.5281/zenodo.15800175 Mirror version (Figshare): 10.6084/m9.figshare.29469518
