Morphology

anencephaly = encephaly (opaque) = an + encephal + y

The combining form 'encephal-' and the prefix 'an-' are technical Greek medical elements unfamiliar to average learners, so the meaning cannot be reliably deduced from common English vocabulary.

Etymology

Anencephaly comes from the Greek parts an- meaning 'without' and encephalon meaning 'brain'. So it literally means 'without a brain', which explains the medical condition where a major part of the brain (and often the skull and scalp) is missing at birth.
