The word “articulate” has its etymological roots in Latin, stemming from the verb “articulare,” which means “to divide into joints” or “to speak distinctly.” This verb itself is derived from “articulus,” a diminutive of “artus,” which translates to “joint.” The development of the meaning involves the idea of something being clear and distinct, much like how joints are separate and defined parts of a structure.
Over time, “articulate” evolved in English to encompass both physical and verbal clarity. Physically, it refers to the connected structure of joints, as in “an articulated skeleton.” In terms of speech and expression, it describes someone who speaks in a clear, effective, and coherent manner, capable of expressing thoughts and ideas well. This dual meaning reflects the connection between the physical act of moving parts smoothly and the intellectual act of expressing thoughts clearly.
