'symmetrical-fingered' originates from the combination of 'symmetrical' and 'fingered'. 'Symmetrical' comes from the Greek word 'symmetria', where 'syn' meant 'together' and 'metron' meant 'measure'.

'symmetria' transformed into the Latin word 'symmetria', and eventually became the modern English word 'symmetrical'.

Initially, 'symmetrical' meant 'having a common measure', but over time it evolved into its current meaning of 'having balanced proportions'.
