Morphology

hyaloid = hyalo (semi-transparent) = hyalo + oid

The formation hyalo + -oid is morphologically regular, but both elements are technical combining forms that many learners will not recognize.

Etymology

The word hyaloid comes from the Greek root hyalos which means 'glass'. The thin, clear membrane in the eye looks like glass, so calling it hyaloid helps you remember it is a transparent, glass-like part of the eye.
