Editing Maranao language (section)

==== Historical development ====
Consonant cluster homogenization occurred in earlier Danao and Subanon, where the articulations of the first consonant followed that of the second (Ex: '''*-gp-''' > '''*-bp-''').

A study by Allison<ref>{{Cite book |last=Allison |first=E. Joe |title=Papers in Philippine Linguistics No. 10 |date=1979 |publisher=The Australian National University |editor-last=Gallman |editor-first=A. |series=Pacific Linguistics Series A – No. 55 |location=Canberra |pages=53–112 |chapter=Proto-Danaw: A Comparative Study of Maranaw, Magindanaw, and Iranun |doi=10.15144/PL-A55.53 |editor-last2=Allison |editor-first2=E. |editor-last3=Harmon |editor-first3=C. |editor-last4=Witucki |editor-first4=J. |doi-access=free}}</ref> noted that Proto-Danao *b, *d, g* were lost in modern Maranao when found before other consonants with the same place of articulation (Ex: '''*bp''' > '''*p'''), but preserved elsewehere.

Lobel<ref name="Lobel and Riwarung 2009b" /> noted that this sound change actually resulted in two features of Maranao phonology: heavy consonants and raised vowels (*{{IPA|[-bpa-]}} > {{IPA|[-pʰɤ-]}}). Aspirated consonants also developed in a similar way in [[Southern Subanon language|Southern (Lapuyan) Subanon]], but without the vowel-raising.
