The combining forms erythr/o and rhod/o share meaning of which color?

• A. White
• B. Red
• C. Blue
• D. Green

Answer: (B)

Both erythr/o and rhod/o indicate the color red. Erythr/o comes from Greek eruthros meaning red, used in terms like erythrocyte (red blood cell) and erythema (reddening of the skin). Rhod/o comes from Greek rhodos meaning rose or red, seen in examples like rhododendron (rose-colored plant) or rhodopsin (a red pigment in the eye). Because they share the meaning red, red is the color these combining forms convey. White would come from roots like albin/o or leuk/o, blue from cyan/o, and green from chlor/o or virid/o, which are not the meanings of these two forms.
