Subanen languages

The Subanen languages (also Subanon and Subanun) are a group of closely related Austronesian languages belonging to the Greater Central Philippine subgroup. Often described as a single language, they are considered by linguists as a dialect cluster more than a monolithic language. Subanen languages are spoken in various areas of Zamboanga Peninsula, namely the provinces of Zamboanga Sibugay, Zamboanga del Norte and Zamboanga del Sur, and in Misamis Occidental of Northern Mindanao. There is also a sizeable Subanen community in Misamis Oriental. Most speakers of Subanen languages go by the name of Subanen, Subanon or Subanun, while those who adhere to Islam refer to themselves as Kalibugan. Jason Lobel (2013:308) classifies the Subanen varieties as follows. Subanen Western Western Subanon Western Kolibugan Nuclear West Nuclear Tawlet-Kalibugan Subanen Salug-Godod Subanen East Nuclear Southern Subanen Central Subanen Northern Subanen Eastern Subanen Lobel (2013:308) lists the following innovations among each of the following subgroups. Nuclear Subanen: *k > Ø Western Subanen: *k > /k/ East Nuclear Subanen: *r > /l/ West Nuclear Subanen: *r > /r/ Western Subanen: *r > /l/ (independently took place, likely due to contact with Tausug, Maguindanaon, Butuanon, Cebuano, and/or Ilonggo, which have also undergone the *r > /l/ shift independently of one another) The following phoneme inventory can be reconstructed for Proto-Subanen: According to Jason Lobel (2013:304-305), the innovations defining Proto-Subanen from Proto-Greater Central Philippine are:

1. *h was lost in all positions in Proto-Subanen.
2. *ʔ was lost word-initially and word-medially, only being retained in word-final position.
3. Reduction of *a to *ə in prepenultimate syllables, as well as in closed penultimate syllables.
4. Addition of a word-initial *g- to all vowel-initlal words following the operation of the previous innovations.
5. Assimilation of consonant clusters into a sequence of either *kC, *gC, or a nasal cluster.
