'asymmetron' originates from Greek, specifically the word 'ἀσύμμετρον (asýmmetron)', where 'a-' meant 'not' and 'symmetron' meant 'measured equally' or 'symmetrical'.

'asymmetron' passed into New Latin/taxonomic usage as a genus name in zoology and is used in modern scientific nomenclature as 'Asymmetron'.

Initially it meant 'not symmetrical' in Ancient Greek; over time it became specialized as a taxonomic name and is now primarily used to denote the genus rather than to describe symmetry.
