Noble
Adilenne is a modern elaboration of the Germanic root 'adal', meaning noble. It likely evolved as a blend of the classic Adeline and the popular suffix -enne, or as a variation of the French name Adeline. While rare, it follows the trend of melodic, multi-syllabic names ending in a soft 'n' sound.
