Etymology

The word 'caffeine' comes from the German word 'Koffein' which is derived from the French word 'café', meaning coffee. The French term is related to the Italian word 'caffè', which also refers to coffee. The chemical caffeine was first isolated from coffee in the early 19th century. By the late 19th century, the term 'caffeine' was adopted into English. The use of caffeine has been traced back to ancient civilizations where it was consumed through various sources such as coffee, tea, and chocolate. Over time, caffeine became popular for its stimulating effects, leading to widespread use in drinks and medications. Today, it remains one of the most commonly used psychoactive substances in the world.
