Which combining form means lymph?

• A. Lymph/o
• B. ren/o
• C. andr/o
• D. bi/o

Answer: (A)

In medical terminology, combining forms name or point to a body part or system and are formed by a root plus a combining vowel. The form that means lymph is lymph/o. It shows up in terms like lymphatic, lymphocyte, and lymphadenopathy, where the sense of the word is tied to the lymph fluid and the lymphatic system.

The other options refer to different parts or concepts: ren/o means kidney (as in renal), andr/o means male or man (as in androgen), and bi/o means life (as in biology). These do not carry the meaning of lymph.
