The word "torture" originates from the Latin verb torquere, meaning "to twist, wrench, or rack." Its past participle, tortus (twisted), gave rise to the Late Latin noun tortura, which literally meant "a twisting" or "torment." This concrete, physical sense of twisting the body on a rack or wheel evolved into the general concept of inflicting severe physical pain. Over time, the meaning broadened further to encompass the infliction of extreme mental or emotional anguish, capturing the abstract sense of being "twisted" in psychological distress.
