This book is a comprehensive lexicon and historical guide that highlights over 3,000 English words derived from Arabic. It challenges the common misconception that Arabic influence was limited to a few exotic terms. Instead, it demonstrates how fundamental words in mathematics (Algebra, Algorithm), science (Alchemy, Alcohol), commerce (Tariff, Check), and even daily life (Sugar, Coffee, Cotton) originated from Arabic. The authors provide the original Arabic root for each word, explain the phonetic evolution it underwent as it traveled through Latin, French, or Spanish, and provide the historical context for when and why these words entered the English lexicon.
