The Arabic/English Thematic Lexicon by Daniel Newman

The Arabic / English Thematic Lexicon is an invaluable resource for all learners of Arabic.
It contains some 8,000 entries, arranged into themes, including flora and fauna, food and drink, the human body, health care, the family, housing, clothing, education, IT, sports, politics, economics and commerce, the law, media, language, geography, travel, religion, arts, science and natural resources. Three appendices cover the names of Arab and selected non-Arab regions, countries and capitals, and international organizations.
The entries in the Lexicon have been drawn from an extensive corpus of contemporary Standard Arabic vocabulary, based on authentic sources. In addition to verbs, nouns and adjectives, the Lexicon includes phrases and commonly used collocations, providing users with the necessary vocabulary in order to communicate effectively and confidently in both written and spoken Standard Arabic.
The Lexicon provides an indispensable complement to Arabic grammar instruction and also serves as a useful reference guide for all Arabic language users.
