Etymology: Ganglion itself came into English from Latin, and it began in Ancient Greek as "gánglion," a word for a swelling or lump, most often a cyst or tumour under the skin. Anatomists later borrowed the term for the knots of nerve tissue that lie outside the brain and spinal cord, so a word for a bump on the body came to name a bundle of nerve cells. Ganglionic is simply ganglion with the adjective-forming suffix "-ic" added, meaning "of or relating to." The suffix traces back through Latin "-icus" and Old French "-ique" before reaching English, where it has been used for centuries to turn nouns into descriptive adjectives such as "ironic" or "fanatic." Ganglionic therefore describes anything belonging to, or characteristic of, a ganglion.
