Did you know?

Stella, the Latin word for "star," shines brightly in the word constellation, but stella words have been favored by scientists to describe earthly things as much as heavenly bodies. Stellar was once used to mean "star-shaped." That use is no longer current, but today biologists and geologists might use one of these synonyms: stellular, stellate, and stelliform. Poets, too, have looked to stella. John Milton used stellar in its infancy when he wrote in Paradise Lost "these soft fires … shed down their stellar virtue." Stellar shot into its leading role as a synonym of star (as when we say "stellar pupil") in the late 1800s.
