Morphology

make + a + clean + breast + of

The literal words ('make', 'clean', 'breast') give a partial clue — 'clean' suggests removing stain and 'breast' can metaphorically stand for conscience — but a B1 learner who only knows the basic meanings is unlikely to infer 'to confess' without prior exposure to the figurative use. The expression is idiomatic/partly metaphorical and somewhat archaic in form, so its meaning is only partially predictable from the constituents.

Etymology

Make a clean breast of comes from a simple image: imagine opening your breast, the chest or heart, and making it clean by telling what you have hidden. That's why it now means 'to confess'.
