Calc- is used to denote which meaning?

• A. Move
• B. In
• C. Heel, stone
• D. About, around

Answer: (C)

Calc- comes from the Latin calx, meaning heel or stone. In medical terms it signals a stone-related idea (as in calculus or calcified tissue) and it also appears in words for the heel bone (calcaneus). So the meaning it conveys here is “heel, stone.” It doesn’t denote movement or general location like “move” or “in/around,” which are expressed with different roots such as mot- or circum-/intra-/peri-.
