Meaning & origin

Zai is a modern, unisex name that entered U.S. records in 2004 and has been gradually rising in popularity, particularly since 2007. It reached its peak rank in 2024, with a 2025 rank of 4,857 and an incidence of about 1 in 85,404 births. The name is concentrated in California, reflecting its appeal in diverse, trend-forward communities. Zai exemplifies the contemporary preference for short, 'Z'-initial names, fitting alongside similar modern coinages like Zayn and Zara.

Zai appears to be a modern coinage, first recorded in U.S. data in 2004. Its rise suggests it was formed from the popular phonetic initial 'Z' combined with a short, catchy sound, possibly influenced by names like Zayd or the place name Zaire. It has no long historical lineage and is primarily used in contemporary English-speaking contexts.
