Which combining form means hand?

• A. Chri/o
• B. Chondr/o
• C. Oste/o
• D. Peri/o

Answer: (A)

The main idea here is recognizing the combining form that names a body part. For the hand, the combining form is chiro- (often written as chri/o in lists), coming from the Greek cheir meaning hand. This form shows up in words related to the hand, such as chiromancy (palm reading) or chiropodist (historically, care of the hand and foot; the hand sense is carried in the root). The other options point to different structures: chondr/o means cartilage, oste/o means bone, and peri/o means around. So the form that specifically means hand is chri/o.
