'adiadokokinesi' originates from Greek, specifically the word 'adiadochokinesia,' where 'a-' meant 'not,' 'diadochos' meant 'successive,' and 'kinesis' meant 'movement.'

'adiadochokinesia' transformed into the modern English word 'adiadokokinesi' through medical terminology adaptation.

Initially, it meant 'inability to perform successive movements,' and this meaning has largely remained the same in modern usage.
