Sollemnia

A long name with a sincere and serious meaning but a gentle sound, Sollemnia comes from the Latin sollemnis meaning "religious, solemn, ceremonial". As such, it may be considered the Late Roman form of the (now more familiar) French names, Solange, Soline, and Solenne.

Nicknames Ema, Sol, Solly, Mia, Nia, and Emi could ground this rare choice

Pronounced suh-LEM-nee-uh.
