'anaemias' originates from Greek, specifically the word 'anaimia', where 'an-' meant 'without' and 'haima' meant 'blood.'

'anaimia' transformed into the Latin word 'anaemia', and eventually became the modern English word 'anaemia' (with 'anaemias' as its plural form) through medical terminology.

Initially, it meant 'lack of blood', but over time it evolved into its current medical meaning of 'a deficiency of red cells or of hemoglobin in the blood.'
