The Conceptual Overlap Between "Laḥn" (Linguistic Deviation) and Dialectal Variation in the Arabic Linguistic Tradition: A Foundational Study in Light of Usage Levels and Contexts of Speech

Abstract

The issue of *al-laḥn* (linguistic deviation or solecism)—its relationship with Arabic dialects and the extent to which they overlap—ranks among the most significant topics that have engaged Arab linguists, both classical and modern. This study examines the origins of this phenomenon—tracing it from early figures like Al-Kisa’i and Al-Zubaidi through to modern scholars such as Ramadan Abd al-Tawwab—while identifying the factors that have sustained it. The study’s significance lies in establishing a foundational understanding of the issue by analyzing historical accounts and examining them against early linguistic traditions. It aims to uncover the relationship between the spread of Islam and the prevalence and nature of *al-laḥn* through the systematic tracking and analysis of relevant texts. Adopting a descriptive-analytical approach, the study presents historical texts containing references to the linguistic dynamics between *al-laḥn* and *al-fuṣḥā* (Standard Arabic). It then analyzes these texts by deriving facts from a precise description of the material, ultimately leading to a set of conclusions. One such instance is the confusion that arose among early linguists between the concepts of *lahja* (dialect) and *lahn* (linguistic deviation or solecism), leading to an overlap between the two. The primary reason for this was the frequent blurring of the boundaries separating them in the scholars' view. Furthermore, the practice of identifying distinct levels of language usage—and subsequently deeming some levels correct while dismissing others as *lahn* or—more often—labeling them as *‘ammiyya* (colloquialism)—was a major factor in perpetuating this conceptual confusion. Linguistic correction served as a form of inquiry into certain dialects; it became evident that many terms previously dismissed as *lahn*—or deviations from Standard Arabic—were, in fact, authentic Arab dialects. This research addresses the overlap between this linguistic legacy and actual dialects, while also elucidating the factors that have sustained this confusion. The language of the Holy Quran differs radically from the language of poetry; it is a record in which all the dialects of the Arabs can be found.
