Unserdeutsch ("Our German"), or Rabaul Creole German, is a
German-based creole language that originated in Papua New Guinea. It
was formed among the New Guinean children residing in a German-run
orphanage in what was then German New Guinea. Oral stories tell a
version that Unserdeursch originated by children sharing stories where
they used German vocabulary with
Tok Pisin grammar, this change in
language is referred to as Relexification.  About 100 native
speakers survive today, most of whom migrated to
Australia after Papua
New Guinea's independence in 1975.
Most speakers of Unserdeutsch are bilingual; speaking either Standard
Tok Pisin or Kuanua. Most speakers are middle-aged or
older, although younger members of the community may comprehend the
language. The descendant of a pidginised form of Standard German which
originated in the
Gazelle Peninsula of New Britain during German
colonial times among the Catholic mixed-race (Vunapope) community.
With increased mobility and intermarriage, it has been disappearing in
the last few decades.
Unserdeutsch presumably influenced the development of its neighbour,
Tok Pisin. Unlike
Namibian Black German in Namibia, it is a creole;
indeed, it is the only creole that developed from colonial German.
