Arc vs. Ark: What's the Difference?

Understanding the distinction between an arc and an ark can be critical. An arc usually refers to a curved shape or segment of a circle, often seen in mathematics, descriptive geometry, or as a narrative term to describe a character’s journey or a storyline in literature. An ark, on the other hand, is primarily a noun that historically refers to a chest or box for storage, or to the biblical Noah's Ark: the large ship built to save Noah, his family, and animal species from the flood.
