Why is the jack playing card called a bower?

The term "bower" for the jack playing card originates from the game of euchre, where the jack is often referred to as the "bower" because it serves as the highest-ranking card in the trump suit, specifically when it is the same color as the trump suit. In this context, the jack of the trump suit is called the "right bower," while the jack of the same color from the other suit is called the "left bower." The term reflects the card's significance and power within the game.
