'asymmetrical' originates from Greek, specifically the word 'asymmetros,' where 'a-' meant 'not' and 'symmetros' meant 'of like measure.'

'asymmetros' transformed into the Latin word 'asymmetricus,' and eventually became the modern English word 'asymmetrical' through Middle English.

Initially, it meant 'not of like measure,' but over time it evolved into its current meaning of 'lacking symmetry or balance.'
