Morphology

bronchoconstrictor = constrictor (semi-transparent) = broncho + constrict + or

The combining form 'broncho-' specifies the airways but is technical; 'constrictor' as 'agent that narrows' is clear.

Etymology

Bronchoconstrictor comes from broncho- 'air tube' and constrictor 'one who squeezes', like a snake that squeezes. So, a bronchoconstrictor is a thing or substance that makes the air tubes narrow and makes it harder to breathe.
