Which root denotes the joint?

Which root denotes the joint?

• A. arthr
• B. uter
• C. pneum
• D. blephar

Answer: (A)

Recognizing combining forms that name body parts. The form arthr- (often seen as arthr/o- or arthro-) means joint, which is why it’s the one denoting the joint. You can see this in terms like arthritis (joint inflammation) and arthroplasty (joint replacement). The other roots point to different structures: uter- refers to the uterus; pneum- refers to air or the lungs; blephar- refers to the eyelid. So arthr- is the correct root for the joint.
