Etymology: The core of this word is a Greek prefix and a sugar name that travelled a long way. "Sákkhar" in ancient Greek meant sugar, and it came from Sanskrit "śárkarā," which referred to grit or gravel, a nod to the granular crystals of sugar. Greek borrowed the sugar sense from Indian sources, and Latin later adopted it as "saccharon" and "saccharum," which gave English the stem "saccharo-." Before it described a sweet crystal, the root pointed at something you might feel crunch between your teeth. The "mono-" part is simpler. It comes from ancient Greek "mónos," meaning "single" or "alone," so the whole word literally means "single sugar." English formed "saccharide," a chemical term for sugar-type compounds, and then added "mono-" to name the simplest class: sugars that cannot be broken down further into smaller sugar units. Glucose and fructose are familiar examples.
