The word "含有" is formed by combining the character "含", meaning "to contain", which is itself composed of the radical "口" (mouth) indicating its semantic field and the component "今" providing historical phonetic guidance, with the character "有", meaning "to have", which is composed of "𠂇" (a hand-like form) and "月" (a variant of "肉" meaning meat) to depict possession; together they create a compound verb meaning "to contain" or "to have within".
