Underground or subterranean.

neutralplacestransport

How it's used

Refers specifically to the physical space beneath the surface of the ground. It is frequently used when discussing infrastructure like tunnels or subway systems, or in more imaginative contexts involving hidden things. Unlike the more abstract or metaphorical uses of underground in English, this term maintains a strong focus on literal location.

Examples

This subway line runs entirely underground.

Common mistake

Avoid using this to describe underground movements or organizations, as it lacks the political or social connotation found in English.
