Tadakhul al-Usul al-Lughawiya wa Atharuhu fi Bina al-Mujam

Tadakhul al-Usul al-Lughawiya wa Atharuhu fi Bina al-Mujam (The Overlap of Linguistic Roots and Its Impact on Lexicon Construction) is a specialized study in Arabic morphology and lexicography by Abd al-Razzaq bin Faraj al-Saidi Tadakhul al-Usul al-Lugha…+1. The work originated as a doctoral dissertation submitted in 1414 AH (1993–1994 CE) at the Islamic University of Madinah, with the expanded title Tadakhul al-Usul al-Lughawiya wa Atharuhu fi Bina al-Mujam al-Arabi min khilal Madrasat al-Qafiya (The Overlap of Linguistic Roots and Its Impact on Arabic Lexicon Construction through the Rhyme School) Tadakhul al-Usul al-Lugha…+1.

Background and Purpose

The study addresses the phenomenon of root overlap (tadakhul al-usul), wherein a single Arabic lexical item can be attributed to more than one root due to phonetic, morphological, or semantic factors Tadakhul al-Usul al-Lugha…+1. Al-Saidi selected the rhyme school of lexicography (madrasat al-qafiya)—which organizes vocabulary by final radical and then by initial radical—as the focus of his study because its lexicons relied primarily on morphological roots for word placement Tadakhul al-Usul al-Lugha….

The author identified several primary objectives for the work: conducting a detailed morphological and analytical examination of root overlap, an area previously touched upon only in scattered remarks such as those in Ibn Jinni's Kitab al-Khasa'is (The Distinctive Attributes); evaluating the negative consequences of this phenomenon on lexical arrangement; identifying potential remedies for future lexicographical projects, notably historical dictionaries; and compiling words misplaced or duplicated across different root entries in classical dictionaries Tadakhul al-Usul al-Lugha…+1.

Structure and Contents

The book is structured into an introduction, a preliminary section, five main parts (abwab), and a conclusion Tadakhul al-Usul al-Lugha…+1:

• Preliminary section (al-Tamhid): Defines the fundamental concepts of roots (al-usul), overlap (al-tadakhul), the dictionary (al-mu'jam), and the rhyme-based arrangement (al-qafiya), explaining the rationale for focusing on this school Tadakhul al-Usul al-Lugha….
• Part One: Titled al-Usul wa-l-Zawa'id (Roots and Augmentatives), divided into three chapters examining roots according to classical and modern linguists, all forms of augmentative letters (regular additions, morphological annexing/ilhaq, and irregular additions), and criteria used to differentiate radical letters from augmentatives Tadakhul al-Usul al-Lugha….
• Part Two: Devoted to overlap occurring within identical morphological templates, covering triliteral with triliteral, quadriliteral with quadriliteral, and quinqueliteral with quinqueliteral roots Tadakhul al-Usul al-Lugha…+1.
• Part Three: Examines overlap between differing base structures, covering triliteral with quadriliteral, triliteral with quinqueliteral, and quadriliteral with quinqueliteral roots Tadakhul al-Usul al-Lugha…+1.
• Part Four: Titled Asbab al-Tadakhul wa-Atharuhu fi Bina Ma'ajim al-Qafiya (Causes of Overlap and Its Impact on the Construction of Rhyme Dictionaries), comprising two chapters:
  • Causes of overlap: Analyzes phonetic and morphological causes, including unity of meaning, metathesis (al-qalb al-makani), consonant substitution (al-ibdal), hamzation and softening, loanword arabization (al-ta'rib), deletion and compensation, morphological extension (al-ilhaq), blending (al-naht), poetic license, assimilation (al-idgham), pluralization patterns, presumed radicalness of affixes, vocalic variations, scribal errors (al-tashif wa-l-tahrif), and reliance on the earlier anagram/permutation school (madrasat al-taqlibat) Tadakhul al-Usul al-Lugha….
  • Lexicographical consequences: Demonstrates three major effects on rhyme dictionaries: misplaced entries, redundant dual or multiple entries for the same word, and the unwarranted inflation of lexicon volume Tadakhul al-Usul al-Lugha….
• Part Five: Titled Athar al-Tadakhul fi al-Naqd al-Mu'jami (The Impact of Overlap on Lexicographical Criticism), divided into two chapters on classical and modern lexicographical critiques Tadakhul al-Usul al-Lugha….
• Conclusion: Outlines the study's findings and recommendations, highlighting that over 2,000 overlapping vocabulary items—representing more than 4,000 overlapping roots—were examined, and identifying six recurring letters responsible for most root confusion: hamza, ta', mim, nun, waw, and ya' Tadakhul al-Usul al-Lugha…+1.

Methodology

The author adopted an integrated approach combining descriptive, historical-comparative, inductive, and critical methods, grounding morphological analysis in classical Arabic grammatical theory, particularly the established positions of the Basran school Tadakhul al-Usul al-Lugha….
