How to make my name mean "Little Tai" in Spanish?

It would be "Tai Peque�a". The adjective for "little" comes AFTER the word it describes, rather than BEFORE, as in English. English is a Teutonic language, Spanish is a Romance language (related to the language of ancient Rome, which was Latin). The "a" ending is used to make it feminine. "ito" or "ita" could be added to "poco" (little) to indicate that it's VERY small or to DESCRIBE something small. e.g. poquito, poquita. The "c" becomes "q" to keep the pronunciation correct. "peque�a" may also denote "youth" as well as size.
