Etymology

Origin of sugar

1250–1300; Middle English sugre, sucre (noun) < Middle French sucre < Medieval Latin succārum < Italian zucchero < Arabic sukkar; obscurely akin to Persian shakar, Greek sákcharon ( see sacchar-)

Explanation

Sugar is the sweet stuff that makes candy and other treats extra delicious, but eating too much of it is bad for you. Sugar isn’t only a food, it’s also an essential part of living cells and a source of energy for all animals. There are two main senses of sugar. First is refined sugar — the crystals that sweeten and preserve many foods. This yummy stuff comes from the sugarcane and sugar beet plants, and really hit the scene in the 18th and 19th centuries when sugar plantations spread and more people could get sugar. The other kind of sugar refers to biochemistry, and these sugars are an important part of the cells of all living things.
