The word 偏离 is formed by combining two meaningful components: 偏, which carries the core idea of being "inclined", "slanted", or "off-center", and 离, which means "to leave", "to depart from", or "to separate". Together, they create a compound where the first character describes the manner of movement (a slanting or veering off-course) and the second character describes the action itself (departing from a point or standard). Visually and conceptually, it depicts the process of starting from a correct or central position and then moving away from it at an angle, hence arriving at its meaning of "to deviate" or "to diverge".
