Morphology

sublight = light (transparent) = sub + light

The adjective is a direct prefixation of 'sub-' (meaning 'below' or 'less than') to 'light' (as in speed of light), so the meaning is inferable.

Etymology

Sublight is made from the parts sub- and light, where sub- means 'below', as in submarine or subway, and light refers to the light we know and the 'speed of light'. So, sublight as an adjective describes speeds or things that are below the 'speed of light', meaning slower than light.
