'Aetomorphae' originates from Greek, specifically the word 'aetos' meaning 'eagle' and 'morphe' meaning 'form'.

'Aetos' and 'morphe' combined in Greek to form 'Aetomorphae', which was adopted into scientific Latin taxonomy.

Initially, it referred specifically to the form or shape of eagles, but over time it evolved to denote a broader taxonomic group including eagles and their relatives.
