Central and South New Guinea languages

The Central and South New Guinea languages (CSNG) are a proposed family of Trans–New Guinea languages (TNG). They were part of Voorhoeve & McElhanon's original TNG proposal, but have been reduced in scope by half (nine families to four) in the classification of Malcolm Ross. According to Ross, it is not clear if the pronoun similarities between the four remaining branches of Central and South New Guinea are retentions for proto-TNG forms or shared innovations defining a single branch of TNG. Voorhoeve argues independently for an Awyu–Ok relationship, and Foley echoes that Asmat may be closest to Awyu and Ok of the TNG languages. Regardless, the four individual branches of reduced Central and South New Guinea are themselves clearly valid families.

Ethnologue (2009) retains only Awyu–Dumut and Ok, calling the branch Ok–Awyu, and places Asmat and Mombum as independent branches of TNG. Loughnane & Fedden (2011) link Ok to the Oksapmin language.Loughnane, Robyn and Fedden, Sebastian (2011) 'Is Oksapmin Ok?-A Study of the Genetic Relationship between Oksapmin and the Ok Languages', Australian Journal of Linguistics, 31: 1, 1-42. However, van den Heuvel & Fedden (2014) argue that Greater Awyu and Greater Ok are not genetically related, but that their similarities are due to intensive contact.van den Heuvel, W. & Fedden, S. (2014). Greater Awyu and Greater Ok: Inheritance or Contact? Oceanic Linguistics 53(1), 1-36. University of Hawai'i Press.

The Somahai languages and Bayono-Awbono may also belong here, but there is little data to go on.

History In the mid 1960s, Alan Healey, a colleague of Laycock, noted connections between the Ok, Asmat, and Awyu–Dumut families. Voorhoeve (1968) expanded on this and coined the name CSNG; his proposal added Trans-Fly and Marind to the mix. Collaboration with McElhanon and his Finisterre–Huon family in 1970 found a connection between them, which was named Trans–New Guinea. Wurm's 1975 expansion of TNG also expanded CSNG, with the addition of Awin–Pa, Bosavi, Duna–Pogaya, East Strickland, Mombum, and Momuna. Ross's recension in 2005 retained nothing from Voorhoeve and only Mombum from Wurm, though the Momuna languages were too sparsely attested for him to classify.
