'unproductive-centered' originates from English, combining 'unproductive' and 'centered', where 'unproductive' means 'not producing or capable of producing' and 'centered' means 'focused on'.

'unproductive' changed from the Latin word 'improductivus' and eventually became the modern English word 'unproductive'.

Initially, 'unproductive' meant 'not producing', but over time it evolved into its current meaning of 'inefficient or not yielding results'.
