Renown 14th century alchemist, theologian and member of the Franciscan order – Ramon Llull (aka “Doctor Illuminatus”) is the first credited with creating the word – alcohol.
"Alcohol is a word that you will not find in dictionaries of Classical Arabic. In the final analysis, however, this word is of Arabic origin. It is derived from the Arabic al-kuhl, which means 'kohl'. In the meaning "essence of wine, spirit," the word later returned to the Arabs and became al-kuhul, Guth explains.
