'kinetic' originates from Greek, specifically the word 'kinesis,' where 'kinein' meant 'to move.' 'Dependent' comes from Latin, specifically the word 'dependere,' where 'de-' meant 'from' and 'pendere' meant 'to hang.'

'kinetic' changed from the Greek word 'kinesis' and eventually became the modern English word 'kinetic.' 'Dependent' evolved from the Latin word 'dependere' through Old French 'dependant' to the modern English 'dependent.'

Initially, 'kinetic' meant 'related to motion,' and 'dependent' meant 'hanging from something.' Over time, 'kinetic-dependent' evolved to mean 'relying on motion.'
