subluminal

Slower than light

Subluminal means slower than the speed of light.

The term appears in physics discussions contrasting ordinary matter and energy with light itself: All spacecraft travel at subluminal speeds.

It's the opposite of superluminal, which describes hypothetical faster-than-light phenomena.

In practice, subluminal covers everything in everyday experience—only light and other electromagnetic radiation travel at light speed.
