Origin

The phrase 毋庸置疑 is formed by combining four characters: 毋, meaning "do not, don't"; 庸, meaning "to use; to employ"; 置, meaning "to put; to place; to plant"; and 疑, meaning "doubtful."

In terms of character construction, 庸 contains the semantic component 庚 ("age") and the phonetic component 同 ("same; identical"). The character 置 uses the semantic component 网 ("net") and the phonetic component 直 ("straight; linear; undeviating"). The character 疑 is composed of several elements, including the semantic components 子 ("child; offspring; descendant"), 止 ("foot"), 𠤕 ("uncertain"), and 匕 ("a kind of spoon in ancient China"), with 止 also serving as a phonetic component alongside 矢 ("arrow").
