"Blend of Sharon and -ica"
The name Sharonica is commonly a female name.
Sharonica has the shape of a modern American formation: the established name Sharon combined with the -ica ending also found in names such as Monica and Veronica. United States birth records show it only from 1974 onward, which is consistent with a twentieth-century coinage rather than an inherited name. No meaning or earlier use is recorded for it in any language.
