'auxoamylase' originates from Greek and New Latin: the Greek prefix 'auxo-' (from 'auxein') meaning 'to grow' combined with 'amyl-' from Greek 'amylon' meaning 'starch', plus the enzyme-forming suffix '-ase' (from New Latin/French 'ase').

'auxoamylase' was formed in scientific New Latin/English by combining Greek-derived elements 'auxo-' and 'amyl-' with the modern enzyme suffix '-ase'; it entered modern English as a technical biochemical term without passing through a distinct medieval English form.

Initially the components signified 'growth' ('auxo-') and 'starch' ('amyl-'); combined as a coined scientific term, the meaning became a specific 'enzyme that digests starch', often named for the context or organism in which it was identified.
