Examples of leuc-​

Leucemia, more commonly spelled leukemia, is one example of a medical term that is related to the combining form leuc-.

Leucemia is “any of several cancers of the bone marrow that prevent the normal manufacture of red and white blood cells and platelets, resulting in anemia, increased susceptibility to infection, and impaired blood clotting.”

The English words leucemia and leukemia come immediately from the German Leukämie, a term in turn based on the Greek leukós.

And what about the -emia portion of the leucemia? It is a combining form that denotes a condition of the blood, and ultimately comes, again through German, from the Greek root haîma, meaning “blood.” Hematology, the study of blood, is another word you may have come across that also comes from Greek.

So, putting it all back together, leucemia has the literal sense of “(disease of) white blood (cells).”
