Definition of leukaemia in English:

noun

[mass noun]
A malignant progressive disease in which the bone marrow and other blood-forming organs produce increased numbers of immature or abnormal leucocytes. These suppress the production of normal blood cells, leading to anaemia and other symptoms.
Example sentences
  • The symptoms of leukaemia vary greatly, depending on the exact type of disease and how advanced it is.
  • There are two basic reasons for carrying out bone marrow transplantation for leukaemia and lymphoma.
  • In people with leukemia, the bone marrow produces a large number of abnormal white blood cells.

Origin

mid 19th century: coined in German from Greek leukos 'white' + haima 'blood'.

More
  • light from (Old English):

    The two words spelled light have different sources. The light referring to the rays that stimulate sight shares an ancestor with Greek leukos ‘white’ (found in leukaemia (mid 19th century) a disease that affects the white blood cells), and Latin lux (source of lucid (late 16th century)). The light referring to weight comes from the same ancient root as lung (Old English)—the lightness of the lungs distinguishes them from other internal organs. This sense of light survives in lights (Middle English), the lungs of sheep, pigs or bullocks, used as food, especially for pets. If someone does something that creates a tense or exciting situation, people might say that they light the blue touch-paper. A touch-paper is a type of fuse that will burn slowly when touched by a spark. It is now only used with fireworks, but in the past would also have been a means for igniting gunpowder. The word lighten (Middle English) ‘shed light on’ is the source of lightning (Middle English).
