The word "睽违" is formed by combining the character "睽", which uses the radical "目" (eye) and the component "癸" primarily for sound, to imply staring away or divergence, with the character "违", which uses the radical "辶" (movement) and the component "韦" for sound, meaning to depart or oppose. Together, they create a compound where both characters semantically contribute to the concept of separation, resulting in a word that denotes being apart or distant.
