Yeah, it's one of the brightest stars in the night sky, right?

Root Explanation

Regulus is derived from the Latin "regulus" (meaning little king or prince), which is a diminutive form of "rex" (meaning king). The term originally referred to a minor or lesser ruler, often used in a figurative sense to denote someone of lesser authority or rank.

Memory Tip

Think of 'regulus' as a 'little king' — 'reg-' relates to kingship, and the suffix '-ulus' indicates something small or diminutive.
