Taiap (or Tayap, also called Gapun, after the name of the village in which it is spoken) is an endangered language isolate spoken by around a hundred people in the East Sepik Province of Papua New Guinea. It is being replaced by the national language and lingua franca Tok Pisin.
The first European to come across Taiap was a German missionary in 1938. The language was not studied by linguists until the 1970s because of the inaccessibility of the region.
Although Donald Laycock (1973) placed Taiap in his Sepik Ramu language family, its structure and vocabulary would be unique for that family, and Ross (2005) found no evidence that it is related to any language of New Guinea. The current extent of Taiap is nearly coincident with what had been an offshore island 6,000 years ago, consistent with the idea that Taiap is a language isolate.
