Which term is correctly spelled for a narrow crest with a sharp ridge?

Explanation:
In glacial geography, a narrow crest with a sharp ridge is called an arete—a knife-edge ridge formed when two glaciers erode parallel valleys, leaving a slim, high crest between them. The standard English spelling is arete (no accent). The other forms don’t fit because they introduce extra letters or endings that aren’t used in the term: arrete adds an extra r, areti ends with i, and areita ends with a.
