Diglossic Continuity in Palestinian Arabic: A Functional Perspective
Introduction
Arabic is often described by non-native observers as a language divided into two separate systems: a colloquial variety used in everyday speech and a formal variety reserved for writing, education, and official contexts. This perception commonly assumes a rigid boundary between colloquial Arabic (ʿāmmiyya) and Standard Arabic (fuṣḥā), sometimes reinforced by anecdotal claims that using Standard Arabic in daily interactions sounds unnatural or inappropriate.
This article argues that such a binary view is misleading. In Palestinian Arabic—and in Arabic more broadly—what exists is not a division between two distinct languages, but a single linguistic system with multiple functional registers. Speakers move fluidly along a continuum of formality and precision, adjusting their level of linguistic elaboration according to context, purpose, and social expectations.
Fuṣḥā as a Register, Not a Separate Language
Standard Arabic is frequently described as a “high” or “formal” language detached from everyday life. However, this characterization obscures its actual linguistic role. Fuṣḥā is not a separate code learned exclusively through schooling; rather, it represents a high-precision register of Arabic characterized by lexical clarity, syntactic balance, and rhetorical control.
The term faṣīḥ in Arabic does not primarily denote formality, but clarity, precision, and eloquence. From this perspective, fuṣḥā is best understood as a stylistic mode rather than an autonomous language. Importantly, elements of fuṣḥā regularly appear within colloquial speech when the communicative situation demands accuracy, respect, emphasis, or rhetorical effect.
Historical Sensitivity to Linguistic Precision
Long before the codification of Standard Arabic, Arabic-speaking communities demonstrated a strong cultural valuation of eloquence and expressive accuracy. Poetic production, in particular, occupied a central role in pre-Islamic and early Islamic society, shaping collective sensitivity to linguistic form, rhythm, and meaning.
Over time, this sensitivity contributed to the emergence of differentiated modes of expression:
a carefully structured, rhetorically balanced style associated with formal discourse, and
a rapid, direct, and interaction-oriented style associated with everyday communication.
Crucially, this differentiation reflects functional specialization, not linguistic separation.
Register Shifting in Actual Language Use
In natural speech, Palestinian Arabic speakers frequently shift between levels of formality within the same conversation. A speaker may rely primarily on colloquial forms but introduce Standard Arabic vocabulary or constructions when greater semantic precision, politeness, or authority is required.
For example, a colloquial expression indicating ability or intention may be replaced by a more formal equivalent when the context calls for careful articulation. Similarly, poetic lines, religious quotations, or formal expressions are often embedded seamlessly into otherwise colloquial discourse.
This phenomenon is best described as register shifting, not code-switching between distinct languages. The speaker remains within Arabic throughout, modulating linguistic choices along a continuum of precision and stylistic elevation.
Arabic as a Unified System with Multiple Levels
From a structural perspective, Palestinian Arabic exemplifies a single linguistic system organized into hierarchical registers. Colloquial speech serves everyday interaction, while higher-register forms are activated for contexts involving abstraction, formality, persuasion, or symbolic authority.
Standard Arabic is therefore not foreign to speakers; it is structurally embedded in their linguistic competence. Its presence is evident in idioms, proverbs, fixed expressions, and even in the grammatical and lexical foundations of colloquial varieties themselves.
An Analogy: Ingredients and Preparation
The relationship between colloquial Arabic and fuṣḥā can be usefully illustrated through a functional analogy drawn from food preparation.
Arabic may be understood as a shared set of linguistic ingredients—lexical roots, morphological patterns, and syntactic structures—while actual speech corresponds to the process of preparation. Different communicative situations call for different modes of preparation, not different ingredients.
Everyday colloquial speech corresponds to a form of linguistic preparation that prioritizes speed, accessibility, and immediate communicative efficiency. It is optimized for informal interaction and rapid exchange. Fuṣḥā, by contrast, corresponds to a more carefully structured mode of preparation, in which balance, proportion, and precision are foregrounded. This mode may involve greater complexity and deliberate organization, but it draws on the same underlying linguistic material.
From this perspective, colloquial Arabic and fuṣḥā are not parallel systems, but different realizations of a shared linguistic substrate, shaped by communicative intent rather than by categorical separation.
Conclusion
The relationship between colloquial Arabic and fuṣḥā should not be understood as a division between two languages, but as a dynamic interaction between registers within one language. Speakers do not alternate between separate systems; they navigate levels of formality and precision according to situational demands.
Recognizing this continuity challenges simplistic models of Arabic diglossia and highlights the importance of viewing language as a flexible, context-sensitive system rather than a set of rigidly separated codes. Such a perspective better reflects actual linguistic practice and provides a more accurate framework for understanding Arabic usage in both social and cognitive terms.
