Etymology: "Adduction" is a Latin-derived term built from "ad" ("to, toward") and "ducō" ("to lead"), so its core sense is literally "a leading toward." The Latin verb "adducere" meant "to bring to oneself" or "to bring forward," and the noun "adductio" carried that same idea of bringing something toward a point. English borrowed the noun directly from Latin, and its sister forms "adduce" and "adduct" came from the same verb, so the three words are close relatives. The word's sense has been narrowed considerably. In its general Latin and English use, adduction meant the act of bringing forward evidence or citing something in support of an argument, which is why "adduce" still means "to cite as proof." In anatomy, the meaning was specialized to describe the movement that draws a limb or body part toward the body's midline, the opposite of abduction, which draws it away. The same ancient verb thus gave English both a logical term for presenting proof and a physiological term for a particular muscular action.
