Morphology

anencephalia = anencephaly (semi-transparent) = an + encephal + ia

The negative prefix 'an-' and noun-forming '-ia' are recognizable, but the root 'encephal-' is a specialized Greek combining form meaning 'brain' and is not a standalone English word, so the composition is only partially transparent to average learners.

Etymology

Anencephalia comes from the Greek parts an- meaning 'without' and encephalon meaning 'brain' or 'in the head'. So anencephalia literally means 'without brain', which helps you remember it is a serious condition where a baby is born missing large parts of the brain.
