Morphology

bolus + hook

This is a domain-specific jargon term: 'bolus' is rare/undefined here and the compound names a specific Jacquard-loom part. Even if a learner knows 'hook', the specialized function (raising/lowering a harness to control warp threads) is not derivable from the constituents, so the meaning is not predictable to a B1 learner.

Etymology

The noun bolus hook comes from old weaving looms. A small part, the bolus hook, literally lifted groups of threads to form patterns, so the name means a piece that 'lifts' or 'guides' threads in the loom.
