"Tai" definitely means "big", too. Hands down. In modern Chinese, people use this word as "excessively" , "very" or whatever, but originally it means "very big" or "great". My name is Jin Tai Xiong (sounds like jin - tie - shong) and this name means "The Great Man".

Tai can be short for Tawanisia (I think that's how it's spelled).
Like Thailand and Taiwan
Tai Tube etc.
