Morphology
start + with + a + clean + sheet
The meaning 'to begin anew' is directly derivable from the constituents: 'start' (begin) + 'with' + 'clean' (unmarked) + 'sheet' (a page), since a clean sheet naturally signals a fresh page to begin on. This compositional metaphor (akin to 'clean slate' or 'blank page') is cross‑linguistically common and follows normal English combination patterns, so a B1 learner who knows the words should infer the intended sense.
Etymology
Start with a clean sheet paints the picture of a fresh, empty sheet of paper with nothing written on it, so you can start again and write something new. That's why it means 'to begin again without old problems'.
