How has the case system been simplified in Faroese?

In the development of Faroese, the original Old Scandinavian declensional system—which featured four cases (nominative, accusative, dative, and genitive)—has undergone simplification.1

In modern spoken Faroese, this system has been reduced to three cases. The genitive case has been effectively eliminated, having been replaced by the use of prepositional phrases or compound words. This shift distinguishes Faroese from Icelandic, which remains more conservative and continues to preserve the full four-case system.12
