Morphology

come + undone

The meaning is directly derivable from 'come' (indicating a change of state) + 'undone' (in disarray or not finished); together they mean 'become undone' (fail, fall apart, or lose control). This follows the common 'come + adjective' compositional pattern found across languages, so a B1 learner who knows both words will generally infer the MWE's meaning.

Etymology

Come undone comes from the image of a knot, stitch, or button that becomes undone and comes apart. So, when something comes undone today, it 'falls apart' or a person 'loses control', like those loose threads.
