The word "贻误" is formed by combining the character "贻", meaning to cause or bequeath, composed of the radical "贝" (treasure) indicating value and the phonetic component "台" suggesting pronunciation, with the character "误", meaning error or delay, composed of the radical "言" (speech) indicating relation to communication and the phonetic component "吴" for sound. In this compound, "贻" contributes the sense of causation and "误" the sense of mistake, together denoting the act of causing delay or error through oversight.
