Tjasa, Tjaša, or Tyasha is a first name diminutive of Tatjana, which originated from a Roman saint Titus Tatius.
Name Tjasa belongs to a group of ...asha names that originated from Russia and Eastern Europe.

Eg. Sasha and Natasha.
Name Tjasa belongs to an exotically mystical female, who never is what she looks like. Tjasa will fool you every time. You might think she looks like a princess from the Eastern World when in reality she is a lion tamer from the Alps... Get the picture?
Respect is a helpful attitude if you find yourself next to a female by this name.
