Morphology

hang + by + a + thread

The image of something 'hanging by a thread' (suspended by a thin cord) directly conveys precariousness, so a learner who knows 'hang' and 'thread' can infer that only a small thing prevents failure. This is a concrete, widely attested metaphor across languages and follows an obvious compositional image, making it immediately comprehensible at B1.

Etymology

Hang by a thread: The idiom hang by a thread comes from the image of something only held up by one thin thread. Because it could fall with the smallest touch, the phrase now means 'in a dangerous situation' or 'close to failure'.
