Isaac Asimov said this quote

There was something ghost-like and insubstantial about gases to these early chemists. They called liquids that turned into gases easily, spirits. Methyl alcohol, they called wood spirit; ethyl alcohol, wine spirit. Even today, alcoholic beverages are frequently referred to as spirits. (Modern Arabs, from whose language the word alcohol was taken, call ethyl alcohol spirit from the English. This is a queer exchange.)
