Tai, which rhymes with Kai, is a unisex name with a range of international references. It means the equivalent of "too much" in Chinese but is also used as a Maori name meaning "the tide" and in Romanian means "yours." While it's only ever ranked in the U.S. Top 1000 as a girls' name, during the height of the popularity of Olympic skater Tai Babilonia, Tai makes a simple intriguing modern choice for either gender.

Skater Tai Babilonia brought this sleek modern name to the world's attention. Pronounced "tie."

Might be asking for trouble, especially when your son reaches the Terrible Twos.
