Which root corresponds to mind?

• A. spir/o
• B. tens/o
• C. ment/o
• D. trache/o

Answer: (C)

Understanding which combining form represents mind is the key idea. ment/o carries the meaning of mind, coming from Latin mens/mentis. It appears in terms like mental, mental health, and mentation (the act or process of thinking). That makes it the best fit for describing something related to the mind. In contrast, spir/o relates to breath or coil, tens/o to tension or stretching, and trache/o to the windpipe, so they do not convey the concept of mind.
