'anangioid' originates from Greek, specifically the prefix 'an-' meaning 'without' and 'angeion' meaning 'vessel', with the suffix '-oid' meaning 'resembling'.

'anangioid' was formed in modern scientific English from Greek roots to describe tissues or structures lacking blood vessels.

Initially, it meant 'resembling the absence of vessels', and it continues to be used in medical and biological contexts to describe avascular structures.
