The Chinese word "含有" is formed by combining two distinct characters: "含", which pictographically originates from the concept of a mouth holding something inside, conveying the idea of containment or enclosure, and "有", which historically derives from a depiction of a hand holding meat, symbolizing possession or existence. When merged, these characters create a compound verb where "含" contributes the sense of physically or abstractly holding within, while "有" reinforces the notion of having or including, resulting in a unified meaning of "to contain" or "to have as a part". This formation leverages the semantic contributions of each component to express a more specific concept than either character alone.
