WORDS THAT USE GLUCO-

What does gluco- mean?

Gluco- is a combining form used like a prefix meaning “sugar” or “glucose and its derivatives.” Glucose is a sugar found in many fruits, animal tissues and fluids, and other sources. Gluco- is occasionally used in scientific terms, especially in chemistry.

Gluco- comes from Greek glykýs, meaning “sweet.” While the Greek letter upsilon is usually transliterated into English as y, it is occasionally adapted as u, as we can see with gluco-. The Latin translation (and perhaps cognate) of glykýs is dulcis, “sweet,” which is the source of sweetness-related terms such as dulcet and, through Italian, dolce vita.
