Fyldish is the official language of the Free State of Sutherfold, in Fyldish called Síreannais or Sírbhéal. Even though the people of the Fold are close to 100% bilingual, since the free state was part of Somery for a considerable period of time, the independence has triggered a sense of pride of the native language, and it's far more common to hear people conversing in Fyldish than in Somerish.

Note that Fyldish and Estron are not the same language, let alone mutually intelligible, although they are distantly related.
