Morphology

obstructor = obstruct (transparent) = obstruct + or

Standard agentive formation from 'obstruct' (+ '-or') creating 'one who obstructs'; semantically direct.

Etymology

Obstructor comes from Latin parts ob- meaning 'against' and struct meaning 'build', the same root you see in structure and construct. That idea of 'built against' helps you remember that an obstructor is a person who blocks or slows actions, often on purpose.
