Maas

Maas is a Dutch masculine given name that originated as a short form of Thomas, itself derived from the Aramaic name Toma, meaning twin. The name has long been used in the Netherlands and Flanders, where clipped forms of longer names were common in everyday speech. It is also associated with the Meuse River, known in Dutch as the Maas, though the river name and the personal name share no etymological connection. Related forms include Maes and the full name Thomas.
