The Qur'an is the living source of all Islamic teaching, and is of singular importance to those interested in Islam and the study of religions. Despite this, there exists a long-felt lack of research tools for English first-language speakers who wish to access the Qur'an in the original Arabic. The Dictionary of Qur'anic Usage is the first comprehensive, fully-researched and contextualised Arabic-English dictionary of Qur'anic usage, compiled in accordance with modern lexicographical methods by scholars who have a lifelong immersion in Qur'anic Studies. Based on Classical Arabic dictionaries and Qur'an commentaries, this work also emphasises the role of context in determining the meaning-scatter of each vocabulary item. Illustrative examples from Qur'anic verses are provided in support of the definitions given for each context in which a particular word occurs, with cross-references to other usages. Frequently occurring grammatical particles are likewise thoroughly explained, insofar as they are used in conveying various nuances of meaning in the text.
