"Blend of Ellie and Anna"
The name Ellieanna is commonly a female name from the "English" origin.
Ellieanna is a modern English formation that joins two familiar elements: Ellie, a short form used for names such as Eleanor, Ellen and Elizabeth, and Anna, a name in English use since the medieval period. The joined spelling is not recorded as an established name in older sources, and it first appears in United States birth records in 2002, which is consistent with a blended coinage rather than an inherited name. Similar combined spellings, such as Elianna, are also in use, so the boundary between Ellieanna as a blend and as a respelling of Elianna is not sharp.
The pronunciation of Ellieanna is el-ee-AN-uh.
