Beloved or cherished
Dayvian is a modern American invention, likely created as a creative blend of the name David and the popular suffix -vian (as seen in names like Jovian or Caspian). While it lacks a long historical lineage, it is often associated with the Hebrew root for 'beloved' due to its phonetic similarity to David.
