Llantrissant - (clan tresh shunt, approximate Welsh pronunciation) or (lan tri sant, American pronunciation). A Welsh placename, home of the Royal Mint, north of Swansea.

Etymologically, Llantrissant is a word composed of "llan" which means a yard, churchyard or clan and "trissant" is derived from an ancient Welsh word, tristre, which has various meanings: a place of ambush, a secret meeting place in trust from which the English word, tryst was derived. So, therefore, a loose interpretation could give it the meaning of "a yard where lovers meet."  However, the historians of Llantrissant, the city, provide the interpretation that it means the Church of Three Saints.
