Morphology

beta-adrenergic + blocker

The compound is compositionally built from a modifier + 'blocker', so 'blocker' clearly signals a drug that inhibits something; however 'beta-adrenergic' is a specialized pharmacological term (relating to adrenaline/epinephrine receptors) that a B1 learner would not be expected to know or transparently derive. Because the agentive meaning is clear but the critical modifier is technical and requires domain knowledge, the overall expression is partly predictable but not fully transparent to general learners.

Etymology

Beta-adrenergic blocker literally says what it does: beta is a type of receptor that senses 'adrenaline', adrenergic connects to that adrenaline signal, and blocker means it stops the signal. Imagine a roadblock that stops fast 'adrenaline' messages to the heart, so the heart beats more slowly and blood pressure goes down, which is why the drug is used to 'slow the heart' and 'lower blood pressure'.
