The word "广场" is formed by logically combining two individual characters, each contributing its core meaning to create a new, unified concept. The first character, "广" (guǎng), carries the fundamental idea of "broad", "wide", or "expansive". It is placed before the second character, "场" (chǎng), which signifies a "ground", "field", or "open space". By placing them together, the expansive quality of "广" directly modifies and describes the type of "场", resulting in the compound meaning of a "broad open space", which is naturally understood as a public square or plaza.
