Morphology

clearance = clear (transparent) = clear + ance

This sense (vertical space available) is the same spatial extension of 'clear' + '-ance' and is straightforward for learners.

Etymology

Clearance comes from the idea of clear meaning 'free from things in the way', like making room under or between objects. That is why clearance is the vertical space under something that lets people or vehicles pass safely.
