Morphology

sectional = section (semi-transparent) = section + al

The form is built from 'section' + '-al', but the technical 'cut-through view' sense is specialized and not fully predictable for learners.

Etymology

Sectional comes from section, which means a 'cut' or 'slice' and comes from the Latin secare, 'to cut', like cutting an apple to see the inside. So a sectional view shows the inside of something as if it has been cut open.
