Morphology

obstruction = obstruct (transparent) = ob + struct + ion

The transition from 'obstruct' to 'obstruction' is a standard noun formation indicating the act or state of blocking.

Etymology

Obstruction comes from Latin parts ob- ('against') and struere ('to pile up'), the same root as structure. Picture stones 'piled up against' a road or pipe — that's why an obstruction is something that physically blocks a passage.
