Where did the word SPA come from?

When we think spa we either think of a small hot tub with jets and hot water, natural hot springs, or a day spa with manicures, pedicures, and back massages. Well the word actually isn't too far off from its connection to its true meaning. Somehow the world became to know the word spa because it is connected to the Belgium resort town of Spa; known for its healthful mineral springs. The word Spa became known and associated with mineral water.
