Relating to larger than normal red blood cells, often associated with certain types of anemia.

Macrocytic → It is formed from "macro-" (from Greek "makros", meaning large) and "cytic" (from Greek "kytos", meaning cell). The word "macrocytic" refers to cells that are larger than normal, particularly in the context of blood cells.
Think of 'macro-' meaning large, and 'cytic' relating to cells — so macrocytic describes large cells.
