The story
Nithya is a Tamil girls' name from the Sanskrit nitya, eternal, constant, unchanging, a word with deep standing in Hindu philosophy where it describes what is permanent against everything that passes. The th spelling is the standard Tamil romanization, distinguishing it from the North Indian Nitya, one of those small spelling signals that tells you which part of India a family calls home. It is rare in US records since 1890, carried by Tamil families in the diaspora, and it appears in our search data more often than the charts would predict, real demand the records have not caught up with. The eternal, worn as a first name: philosophy compressed into six letters. The slight spelling difference carries real linguistic information without changing the name's central idea.
