The word 打扰 is formed by combining two characters, each contributing a core action to create a unified concept. The first character, 打 (dǎ), originally meaning "to strike", here extends to the abstract sense of "to initiate an action". The second, 扰 (rǎo), means "to disturb" or "to harass". When joined, they depict the initiating action (打) that causes a disturbance or interruption (扰), thus conceptually forming the idea of "to bother" or "to disturb" someone by imposing upon their state or activity.
