elixir: [14] Although nowadays we think of an elixir as liquid, it probably originated in the Greek word for ‘dry’, xērós (whence English xerox). From this was derived a term for a ‘dry’ powder for treating wounds, xérion, and it has been speculated that this was borrowed by Arabic as (with the definite article al) aliksīr. Medieval alchemists used this as a word for a substance which could change base metals into gold, and also for a substance (according to some the same substance) which could confer immortality (known more fully as the elixir of life).
