Morphology

beta + blocker

The word 'blocker' transparently signals an agent that inhibits something, so learners can guess this is a substance that 'blocks' whatever 'beta' refers to. However, 'beta' here names a technical receptor subtype (beta-adrenergic) and the specific medical effect (lowering blood pressure/heart rate) is domain-specific and not predictable for a B1 learner, making the overall expression only partially transparent.

Etymology

Beta blocker The name beta blocker comes from how the medicine works. It 'blocks' special beta switches on heart cells that tell the heart to beat faster, so the blocker makes the heart 'slow down' and blood pressure 'fall'.
