Kashshaf Istilahat al-Funun wa al-Ulum (The Revealer of Technical Terms of the Arts and Sciences) is an encyclopedic dictionary of technical terminology compiled by the Indian scholar Muhammad Aala al-Thanawi (d. 1191 AH / 1777 CE) Idah al-Maknun fi al-Dhay…+1. Completed in 1158 AH (1745 CE), the work defines and contextualizes technical terms across the Islamic traditional, linguistic, and rational sciences Kashshaf Istilahat al-Fun…+1.

Composition and Purpose

Al-Thanawi completed the rough draft of his compilation in 1158 AH after several years of research Kashshaf Istilahat al-Fun…+1. In the introduction, he explains that he was prompted to write the work because students in his time frequently struggled with the specialized terminologies unique to each field, often failing to locate definitions across scattered treatises al-Durr al-Naqi fi Sharh …+1. Having completed his studies in Arabic and traditional disciplines under his father, he turned toward the philosophical and mathematical sciences through independent study of compendia, gathering technical terms across diverse subjects into a single reference work to spare students time and effort Nuzhat al-Khawatir wa Bah…+1.

Structure and Methodology

The work opens with an extensive theoretical introduction (muqaddimah) addressing the classification of sciences into theoretical and practical disciplines, Arabic linguistic disciplines (such as grammar, morphology, and rhetoric), Islamic legal and religious sciences (such as kalam, tafsir, and usul al-fiqh), and universal rational sciences (such as logic, mathematics, and natural philosophy) Kashshaf Istilahat al-Fun…+1. Within this introduction, al-Thanawi details the philosophy of scientific classification, definitions by essence and accident, and what he termed the "eight headings" (al-ru'us al-thamaniyah): purpose, utility, title, author, parent discipline, rank, divisions, and educational methods Kashshaf Istilahat al-Fun….

The main body comprises 3,045 technical terms organized into two primary divisions (fannan) Kashshaf Istilahat al-Fun…+1:

• An extensive first division devoted to Arabic technical terms, arranged into chapters (abwab) according to their first root letters and sections (fusul) according to their final letters Kashshaf Istilahat al-Fun…+1.
• A concise second division placed toward the end, containing non-Arabic and Persian expressions arranged alphabetically Kashshaf Istilahat al-Fun…+1.

In defining terms, al-Thanawi moves methodically from the literal linguistic meaning to transmitted, rational, and specialized scientific usages, citing authoritative classical texts and scholars al-Durr al-Naqi fi Sharh …+1. Approximately one-quarter of the explanatory material in the original text was composed in Persian, while the remainder was written in Arabic Kashshaf Istilahat al-Fun….
