Morphology

alpha + blocker

The compound transparently signals a 'blocker' of something labeled 'alpha' — a learner who knows 'blocker' and 'alpha' could infer it blocks an entity called alpha. However, the precise medical meaning (blocking alpha-adrenergic receptors and its clinical use for blood pressure/prostate issues) is specialised jargon that a B1 learner would not deduce from the constituents alone, so the expression is only partially predictable.

Etymology

Alpha blocker comes from the name of tiny cell parts called alpha receptors and the word blocker, which means 'to stop' them. So an alpha blocker is a medicine that 'stops' those signals, letting blood vessels and the prostate relax to lower blood pressure and help urine flow.
