Erica spelled backward
Acire is a modern ananym, created by spelling the name Erica in reverse. While it lacks a traditional etymological root, it is often chosen by parents looking for a unique variation of a classic name. Because it is a mirror of Erica, it indirectly shares that name's Germanic associations with eternal rule.
