Mount Brown, also known as Manubaran after the local pronunciation of Mount Brown, is comprised of perhaps three closely-related languages, Doromu-Koki, Gebi and Maria, spoken in the south central portion of Papua New Guinea's Central Province (Dutton 1970: CITE, 978.)

===== Historical phonology =====
**[under construction]**\\
\\

Proto-Mount Brown had 13 or 14 consonants and 5 vowels as follows:

|< - 60px 60px 60px 60px 60px >|
|  *m  |  *n  |      |      |        |
|  *p  |  *t  |  *s  |  *k  |   *ʔ   |
|  *b  |  *d  |      |  *g  |        |
|      |      |      |      |  [*h]  |
|  *w  |  *ɾ  |  *j  |      |        |


|< - 60px 60px 60px >|
|  *i  |      |  *u  |
|  *e  |      |  *o  |
|      |  *a  |      |

Any consonant except /*ʔ *h/ may occur initially or medially. Glottal stop /*ʔ/ and unoccluded fricative /*h/ have not been heard initially. Neither final consonants nor consonant clusters occur.\\
\\

Vowel length is not contrastive. There is no obvious distinction between diphthongs and sequential vowels. The following vowel sequences have been observed:

|< - 60px 60px 60px 60px 60px 60px >|
|      |  *i   |  *u   |  *e   |  *o   |  *a   |
|  *i  |  ---  |       |  *ie  |       |  *ia  |
|  *u  |  *ui  |  ---  |  *ue  |       |       |
|  *e  |  *ei  |  *eu  |  ---  |  *eo  |       |
|  *o  |  *oi  |       |  *oe  |  ---  |       |
|  *a  |       |  *au  |  *ae  |  *ao  |  ---  |

Consonants correspond as follows:

|< - 80px 80px 80px 80px >|
|  Mt. Brown  |  Doromu  |  Gebi  |  Maria  |
|     *m      |    *m    |   m    |   *m    |
|     *n      |    *n    |   n    |   *n    |
|     *p      |    *ɸ    |   p    |   *ɸ    |
|     *t      |    *t    |   t    |   *h    |
|     *s      |    *s    |   h    |   *h    |
|     *k      |    *k    |   k    |   *ʔ    |
|     *ʔ      |    *ʔ    |   ʔ    |   *ʔ    |
|     *b      |    *b    |   b    |   *b    |
|     *d      |    *d    |   d    |   *d    |
|     *g      |    *g    |   g    |   *g    |
|     *h      |    *ø    |   ø    |   *h    |
|     *w      |    *w    |   w    |   *w    |
|     *ɾ      |    *ɾ    |   ɾ    |   *ɾ    |
|     *j      |    *j    |   j    |   *j    |

Vowels and vowel sequences correspond as follows:\\
\\

…\\
\\

These correspondences are exemplified as follows, with Gebi attestations drawn from Grist (1925-1926: 93) and presented in their original orthography save for the substitution of <j> for Grist's <y>. Loans from Oceanic are included here under the assumption that they were already established prior to the break up of Proto-Mount Brown.\\

===== Loans from Central Papuan Tip =====
Mount Brown has a number of roots which originated as loans from the Central Papuan Tip subgroup of Oceanic (q.v. Capell 1943: 11-19, 20-37, Dutton 1970: 926-950, Kassel and Potter 2009: 40-49.) We assume these loans to predate the breakup of Proto-Mount Brown, an assumption supported by the fact that /*susu/ is no longer the main term for “breast” in Motu, Sinaugoro or Keapara (cf. /*ɾata/) while the meaning of /*ɣade/ “chin” has changed to “tooth” in both Doromu-Koki and Maria:
