Blackjack is formed from "black" (from Old English "blæc", meaning dark or the color black) and "jack" (from Middle English "jakke", a diminutive form of "John", often used to refer to a man or a common fellow). The term originally referred to a card game that became popular in the United States, where the goal is to reach a total of 21 points, often represented by the ace and a ten-value card, which can be seen as a 'jack' in some contexts.
Think of the color 'black' representing the dark cards in the game and 'jack' referring to a common man or card, helping you remember that blackjack is a card game involving these elements.
