solar

Definitions

From Latin sōl (the sun) + -aris (relating to) = 'of the sun.' This is the sun branch of the root, not the 'alone' branch. Solar covers anything tied to the sun: the solar system, a solar eclipse, and — in modern use — solar power and solar panels.

Why It Means This

Solar is the everyday face of Latin sōl. It started as a purely astronomical word — the solar system, the solar year — but the energy revolution gave it a second life: solar power, solar panels, solar farms. Whenever you see solar, picture the sun overhead, never a lone figure; this word belongs entirely to the sun branch.
