The official language in the Faroe Islands is Faroese. Faroese is a Germanic language deriving from Old Norse and is closely related to Icelandic, Norwegian, Danish, and Swedish.
Danish is the second language in the Faroe Islands and practically everyone can speak and write Danish. Icelandic, Norwegian and Swedish are understood and spoken by many Faroese, and most people are capable of communicating in English too.
It is possible to carry out research work and give lessons to bachelor students in the Faroe Islands without acquiring knowledge of Faroese. However, Faroese is the working language at all research institutions, and learning Faroese will make it easier to integrate professionally and privately.
