Morphology

accommodational = accommodation (semi-transparent) = accommodation + al

The adjective is a regular suffixal derivative of the technical noun 'accommodation', but the specialized optical sense is not obvious for many learners.

Etymology

The word accommodational comes from accommodate, made from the Latin parts ad- 'to' and commodare 'make fit'. So accommodational describes how the eye's lens changes shape to 'make things fit' so you can see clearly at different distances.
