'symmetric' originates from Greek, specifically the word 'symmetria,' where 'syn-' meant 'together' and 'metron' meant 'measure.'

'symmetria' transformed into the Latin word 'symmetria,' and eventually became the modern English word 'symmetric' through Middle English.

Initially, it meant 'measured together,' but over time it evolved into its current meaning of 'having similarity in size, shape, and relative position of corresponding parts.'
