'aleukaemic' originates from Greek, specifically the word 'leukos,' where 'a-' meant 'without' and 'leukos' meant 'white.'

'aleukaemic' changed from the Greek word 'aleukos' and eventually became the modern English word 'aleukaemic.'

Initially, it meant 'without white,' referring to the absence of white blood cells, and this meaning has largely remained the same in modern usage.
