The word "琶洲" is formed by combining the character "琶", derived from the term "琵琶" (pípá, a Chinese lute), likely for its phonetic association or historical reference, with the character "洲", meaning "river island" or "sandbar", which describes the physical geography of the area. This combination results in a toponym that identifies a specific place, with "洲" indicating its location in a river and "琶" distinguishing it through sound or contextual meaning.
