Subspace
Subspace, occasionally spelled sub-space, is an integral part of the universe, distinct from yet coexistent with normal space and its respective space-time continuum. 
Subspace has an infinite number of domains. Geordi La Forge compared it with "... a huge honeycomb with an infinite number of cells." () One of these domains could also be called a subspace spectrum. In 2367, the  picked up frequencies across the entire electromagnetic and lower subspace spectrum. ()

Subspace and normal space sometimes connected together in the form of space anomalies or subspace anomalies like 
 Astral eddy (),
 Subspace compression anomaly (), 
 Subspace rift (), 
 Subspace rupture (), 
 Subspace sinkhole (), 
 Subspace tear () or 
 The Void ()

However, in some regions an interfold layer forms between the two realms. ()

Tetryon particles are a form of subatomic particle which can only exist naturally in subspace. If they are released into normal space, they exhibit erratic properties. This can only occur when the fabric of subspace comes into contact with normal space in some manner.

Subspace was the medium by which faster-than-light transit was possible. Warp travel utilized subspace to create a warp bubble for ships to safely traverse. Without subspace, warp travel would become impossible. ()

Some species, such as the solanogen-based lifeforms, were indigenous to subspace. ()
