The word "kahve" itself is thought to be derived from the Arabic word "qahwah". Coffee was first cultivated in Ethiopia and then spread to Yemen, where it became a popular drink and a key part of social life. The Ottoman Empire, which ruled over much of the Middle East, North Africa, and parts of Europe, adopted coffee and its associated culture. The word "kahve" spread throughout the Ottoman Empire, and eventually into Europe, where it was adapted into "cafe".
So, the next time you enjoy a cup of coffee at a cafe, remember that you're partaking in a tradition that stretches back centuries and across continents!
