'anti-catalase' originates from Greek and New Latin, specifically the prefix 'anti-' (Greek 'anti') and the New Latin/Modern scientific word 'catalase' (from Greek 'katalusis'), where 'anti-' meant 'against' and 'katalusis' meant 'dissolution' or 'loosening'.

'anti-catalase' formed by combining the Greek-derived prefix 'anti-' with the enzyme name 'catalase' (which entered scientific vocabulary via New Latin from Greek 'katalusis'); the compound arose in modern scientific English as a technical term for antibodies or agents acting against catalase.

Initially the elements meant 'against' + 'dissolution' in their Greek roots, but in modern usage 'anti-catalase' specifically denotes being 'against the enzyme catalase' or an antibody/inhibitor targeting catalase.
