'anaplerosis' originates from Greek, specifically the word 'anaplērōsis,' where 'ana-' meant 'up, again' and 'plēroun' meant 'to fill.'

'anaplērōsis' was adopted into New Latin as 'anaplerosis' and eventually became the modern English word 'anaplerosis.'

Initially, it meant 'filling up again,' but over time it evolved into its current scientific meaning of 'restoring a deficiency, especially in metabolic cycles.'
