Sabahan languages

The Sabahan languages are a group of Austronesian languages centered on the Bornean province of Sabah.

Blust (2010)
The constituents are separated into two families in Blust (2010):


 * Northeast Sabahan
 * Bonggi
 * Ida’an
 * Southwest Sabahan
 * Dusunic (15)
 * Paitanic (4)
 * Murutic (7)
 * Tidong (5)

Lobel (2013)
Lobel (2013b, p. 47, 361) proposes the following internal classification of Southwest Sabahan, based on phonological and morphological evidence.
 * Greater Dusunic
 * Dusunic
 * Bisaya-Lotud
 * Paitanic
 * Greater Murutic
 * Murutic
 * Tatana
 * Papar

Lobel (2013:367–368) lists the following Proto-Southwest Sabahan phonological innovations that were developed from Proto-Malayo-Polynesian. (Note: PSWSAB stands for Proto-Southwest Sabahan, while PMP stands for Proto-Malayo-Polynesian.)
 * PMP *h > PSWSAB Ø
 * PMP *a > PSWSAB *ə / _# (possibly be an areal feature in Sabah or northern Borneo, since this is also found in Idaanic)
 * PMP *R > PSWSAB *h / (a,i,u)_(a,ə,u)
 * PMP *R > PSWSAB *g / ə_
 * PMP *-m- > ø in PSWSAB reflexes of the PMP pronoun forms *kami ‘1EXCL.NOM’, *mami ‘1EXCL.GEN’, and *kamu ‘2PL.NOM’
 * Reduction of most PMP consonant clusters to either singletons or prenasalized clusters
