Which term describes the stars that are always hidden from view from a particular location on Earth?

The term that describes stars that are always hidden from view from a particular location on Earth is "never rise stars." These stars are located below the horizon for that specific geographical location due to the curvature of the Earth. As the Earth rotates, we experience different stars coming into view and setting below the horizon, but certain stars remain perpetually out of sight depending on the observer's latitude and the star's position in the sky.

"Nadir stars" refers to celestial objects that lie directly beneath an observer's feet, but this does not imply that they are hidden from view; rather, it simply designates their position in relation to the observer's point on the Earth. "Celestial stars" is a more general term that does not specifically address the visibility of stars from a particular location. "Fixed stars" typically refers to stars that do not exhibit noticeable motion against the celestial sphere from our perspective, but this term does not inherently relate to the visibility of these stars based on Earth's rotation or position. Thus, "never rise stars" is the most appropriate term for stars that cannot be seen from certain locations on Earth.
