The word "傍边" is formed by combining the characters "傍" and "边". "傍" is a phono-semantic compound consisting of the radical "亻" (person) and the component "旁", which provides both sound and the meaning of "side". "边" is also a phono-semantic compound with the radical "辶" (movement) and means "side" or "edge". Together, they create a word where "傍" denotes proximity and "边" specifies the side, resulting in the meaning "by the side" or "nearby".
