What ancient language does candy come from?

The word "candy" doesn't come from an ancient language! It has a more recent origin:

* Middle English: "candy" comes from the Middle English word "candied", which meant "preserved with sugar". This word itself likely came from the Old French word "candir" meaning "to crystallize".

So, while the word itself isn't ancient, the concept of sweet treats made with sugar has a long history, going back to ancient civilizations that cultivated sugar cane and learned to process it into syrup and eventually crystallized sugar.
