Moonie

Moonie is a girl's baby name of Old English origin, a playful diminutive form referring to the moon, from the Old English mōna. The -ie ending gives it a warm, informal quality that transforms the cosmic moon into something affectionately small and personal.

Moon-names have surged in the 21st century as parents seek celestial and nature-connected names. Moonie takes the beloved moon concept and wraps it in the warmest, most informal diminutive possible — like calling the moon your personal pet name, turning cosmic grandeur into intimate affection.
