'symmetrically-divided' originates from the Greek word 'symmetria,' where 'sym-' meant 'together' and 'metron' meant 'measure,' combined with the English word 'divide,' from Latin 'dividere,' meaning 'to separate.'

'symmetria' transformed into the Latin 'symmetria,' and eventually became the modern English word 'symmetrical.' 'Dividere' transformed into the Old French 'diviser,' and eventually became the modern English word 'divide.'

Initially, 'symmetria' meant 'commensurability,' but over time it evolved into its current meaning of 'having balanced proportions.'
