bourse

The word 'bourse' entered English directly from French in the 16th century, where it meant 'purse' or 'exchange'. The French term derives from the name of the Van der Buerse family, merchants in Bruges whose house, marked by three purses (bursae), became a meeting place for merchants and financiers in the 13th century. This semantic shift from a family name to a place of commerce mirrors the evolution of the Latin word bursa (a bag or pouch) into a term for a treasury or fund. Thus, the modern abstract meaning of a financial exchange retains the core historical concept of a central location for the handling of money and securities.

The word is a simplex loanword from French. It does not contain separable morphemes within its modern English spelling.
