Morphology
The phrase combines 'accordion' (evoking the bellows' zig‑zag shape) with 'fold' (a crease), so the meaning — a series of alternate parallel folds like an accordion — is directly inferable from the constituents. This metaphorical naming is visually transparent and common cross‑linguistically, so a B1 learner who knows both words would readily grasp the sense.
Etymology
Accordion fold comes from the musical instrument accordion, whose folds are the 'bellows' that open and close in a zig-zag. So, the name now describes a way of folding paper into a compact stack that can be opened out, exactly like an accordion.
