Meaning & origin

Cynithia first appeared in U.S. Social Security records in 1953, a time when name variations were increasingly creative. It reached its peak popularity in 1966, though it never entered the top 1,000 names. The name remains very rare, with a stable trajectory in recent decades, and no single state recorded enough usage to count among top birth regions. As a respelling of Cynthia, it shares the gentle feminine sound that made Cynthia a mid-century standard, but Cynithia's unique spelling gives it a quietly distinctive place in the landscape of American given names.

Cynithia is a modern respelling of Cynthia, an English name derived from Greek "Κυνθία" (Kynthia), meaning "woman from Mount Kynthos" on Delos, the birthplace of Artemis. The spelling with an 'i' likely arose as a phonetic variant or typographical error in mid-20th century America. It has never been common, appearing sporadically in Social Security records.
