The word 大局 (dàjú) is a compound noun formed by combining the character 大 (dà), meaning "big" or "great", with 局 (jú), which originally referred to a chessboard or game but metaphorically extends to mean "situation", "layout", or "overall picture". Together, they create a conceptual blend where 大 amplifies the scale and importance of the 局, resulting in a term that literally means "big situation" but is used idiomatically to signify "the overall situation", "the broader picture", or "the general interests", often implying a strategic, macro-level perspective that transcends minor details or individual concerns.
