Morphology

complementary + distribution

The components 'complementary' (acting to complete) and 'distribution' (arrangement or spread) give a general hint that two things occupy different but matching parts, so learners may infer a relation of non-overlap. However, the precise linguistic meaning—that related sounds occur in mutually exclusive environments—is technical and not fully predictable from the constituents alone, so partial knowledge but not full comprehension is likely for a B1 learner.

Etymology

Complementary distribution is like two puzzle pieces that fit different spaces. Here complementary means they fit together without overlap and distribution means where each piece appears, so the phrase describes two sounds that occur in different places and are never 'together'.
