Combination name; possibly derived from Nia and Asia
Niasia is a modern American invented name, likely created by blending the Swahili name Nia, meaning 'purpose', with the name Asia, referring to the continent or the Greek mythological figure. It gained some usage in the late 20th century within African American communities as part of a trend of rhythmic, multi-syllabic names ending in -sia.
