He enjoyed a glass of applejack during the winter festival.
Applejack is formed from "apple" (from Old English "æppel", meaning the fruit of the apple tree) and "jack" (from Middle English "jakke", a diminutive form of "Jack", often used to refer to a man or a boy). The term originally referred to a type of alcoholic beverage made from apples, typically apple brandy, and the name reflects the fruit used in its production along with a colloquial term for a man.
Think of 'apple' as the fruit used to make the drink and 'jack' as a common name for a man, which helps you remember that applejack is a drink made from apples.
