Morphology

hemianopsia = anopsia (opaque) = hemi + anopsia

A specialised medical term formed from Greek combining forms ('hemi-' + 'anopsia'); the elements are not familiar productive morphemes for average learners, so the composition is not readily guessable.

Etymology

Hemianopsia comes from Greek parts hemi- meaning 'half' and -opsia meaning 'sight', a root you can compare to the 'opt' in optical. So hemianopsia is the medical name for losing sight in one half of your view.
