Meaning & origin

Sonjia is a modern respelling of Sonia, which itself derives from the classic name Sophia. First recorded in the United States in 1938, it peaked in popularity in 1967, when it was given to a modest number of baby girls. Since then, its usage has been stable but very low, and in 2025 it still remains outside the top 1,000 names. The name never associated strongly with any particular state, reflecting its sparse but nationwide distribution. As a variant spelling, Sonjia offers an unconventional twist on a more traditional name.

Sonjia is a modern respelling of Sonia, a name that originated as a Russian diminutive of Sofiya (derived from Greek Sophia, meaning wisdom). Sonia became popular in English-speaking countries in the 19th and 20th centuries, and creative spellings like Sonjia emerged in the mid-20th century.
