What term refers specifically to a burning sensation?

The term that refers specifically to a burning sensation is rooted in the combining form "caus/o." This prefix is derived from the Greek word "kaustos," which means "burned" or "burning." In medical terminology, "causalgia" refers to a painful burning sensation that is often associated with nerve damage.

The other terms do not pertain specifically to a burning sensation. "Albin/o" relates to whiteness and is often used in terms associated with lack of pigmentation. "Bi/o" refers to life or living organisms and is commonly found in biological terms. "Aden/o" pertains to glands. Thus, the specificity of "caus/o" in conveying a burning sensation makes it the correct choice in this context.
