The word 偏执 is formed by combining the character 偏, meaning "biased" or "deviant", with 执, meaning "to hold" or "to persist". 偏 incorporates the human radical 人 and the phonetic component 扁, conveying a sense of partiality or distortion. 执 derives from an ancient pictograph representing a hand grasping an object, implying steadfastness or fixation. In combination, 执 intensifies 偏, resulting in a compound that denotes rigid adherence to a skewed perspective, hence meaning "paranoia" or "obsession".
