Ṭibāq combines contrasted meanings, as in night and day. Murāʿāt al-naẓīr groups related but not opposing concepts, as in sun, moon and stars. Jamʿ brings several things under one judgment; tafrīq distinguishes items of a shared kind.
Contrast versus thematic association distinguishes the first pair; one shared judgment versus a differentiating judgment distinguishes the second. These are relationships in sense, not merely sound.
