What is the meaning of word whiskey?

Whiskey (or whisky) is a type of distilled alcoholic beverage made from fermented grain mash. The word "whiskey" is derived from the Gaelic word "uisce beatha", which means "water of life". Whiskey is typically made from malted barley, but other grains such as corn, wheat, and rye can also be used. The grain is mashed and fermented with yeast, and then distilled to create a clear spirit. The spirit is then aged in oak barrels, which gives it its characteristic flavor and color. Whiskey can be produced in many different countries, and each country has its own unique style of whiskey.
