'asymmetral' originates from Greek, specifically the word 'asymmetria' (ἀσυμμετρία), where the prefix 'a-' meant 'not' and 'symmetria' meant 'agreement in measure or proportion'.

'asymmetral' changed from Late Latin/Medieval Latin word 'asymmetria' and, in English, the adjective was formed by adding the suffix '-al' to produce the form 'asymmetral'.

Initially, it meant 'not in proportion; lacking symmetry', and over time it has been used to mean the modern sense of 'not symmetrical' or 'not exhibiting symmetry'.
