Morphology

chalk + and + cheese

Although the constituents 'chalk' and 'cheese' are concrete and clearly different items, allowing a learner to infer some sense of contrast, the specific conventionalized meaning 'completely different/incompatible' comes from a fixed cultural pairing rather than straightforward compositional logic. The expression gives a hint of opposition but its idiomatic, conventionalized use is not fully predictable to a B1 learner who has not seen the phrase before.

Etymology

Chalk and cheese may come from the simple image of chalk as a dry white thing used for writing and cheese as soft food you eat. Because they look and are used so differently, people use the phrase to say two things are 'completely different'.
