Evidence of the existence of soup can be found as far back as about 6,000 BC.  Boiling was not a common cooking technique until the invention of waterproof containers (which probably came in the form of clay vessels). Animal hides and watertight baskets of bark or reeds were used before this. To boil the water hot rocks were used. This method was also used to cook acorns and other poisonous plants.

The word soup comes from French soupe (“soup”, “broth”), which comes through Vulgar Latin suppa (“bread soaked in broth”) from a Germanic source, from which also comes the word “sop”, a piece of bread used to soak up soup or a thick stew.

The word restaurant (meaning “[something] restoring”) was first used in France in the 16th century, to describe a highly concentrated, inexpensive soup, sold by street vendors, that was advertised as an antidote to physical exhaustion. In 1765, aParisian entrepreneur opened a shop specializing in such soups. This prompted the use of the modern word restaurant to describe the shops.

“The etymological idea underlying the word soup is that of soaking. It goes back to an unrecorded post-classical Latin verb suppare soak’, which was borrowed from the same prehistoric German root (sup-) as produced in English sup and supper. From it was derived the noun suppa, which passed into Old French as soupe. This meant both piece of bread soaked in liquid’ and, by extension, broth poured onto bread.’ It was the latter strand of the meaning that entered English in the seventeenth century. Until the arrival of the term soup, such food had been termed broth or pottage. It was customarily served with the meat or vegetable dishes with which it had been made, and (as the dreivation of soup suggest) was poured over sops of bread or toast (the ancestors of modern croutons). But coincident with the introduction of the world soup, it began to be fashionable to serve the liquid broth on its own, and in the early eighteenth century it was assuming its present-day role as a first course.”

“Our modern word “soup” derives from the Old French word sope and soupe. The French word was used in England in the in the form of sop at the end of the Middle Ages and, fortunately, has remained in the English language in its original form and with much its original sense. We say “fortunately” because it is clear that nowadays a “sop” is not a “soup.” The distinction is important. When cooks in the Middle Ages spoke of “soup,” what they and the people for whom they were cooking really understood was a dish comprising primarily a piece of bread or toast soaked in a liquid or over which a liquid had been poured. The bread or toast was an important, even vital, part of this dish. It was a means by which a diner could counsume the liquid efficiently by sopping it up. The bread or toast was, in effect, an alternative to using a spoon…Soups were important in the medieval diet, but the dish that the cook prepared was often a sop that consisted of both nutritious liquid and the means to eat it. The meal at the end of a normal day was always the lighter of the two meals of the day, and the sop appears to have had an important place in it. In fact it was precisely because of the normal inclusion of a sop in this end-of-the-day meal that it became called “souper” or “supper.”
