Etymology: Ancient Greek physicians used "paralysis" for the loss of movement or feeling in a body part. The word combines "para," meaning "beside" or "aside," with "lysis," from "lyein," meaning "to loosen." The literal image is of a limb loosened from its normal function, so that it no longer obeys the will. "Paralusis" is a rare variant spelling that keeps the Greek ending closer to its source. Its sense of a voice that fails under emotional pressure is a modern extension, applying the old picture of a faculty that stops responding from muscles to speech.
