curiosity (English)

Where does "curiosity" come from?

The word curiosity traces back to the Latin term cūriōsitās, which described a sense of carefulness or inquisitiveness. It entered English through the Anglo-Norman word curiouseté, eventually replacing the native Old English term firwitt. Over time, its meaning expanded from describing a person's desire to learn to also referring to the unique and finely crafted objects that spark such interest.
