BONGGI
(Sabah, Malaysia; Austronesian, Western Malayo-Polynesian)		 For more information about metathesis in this language, click on the following links:
Summary:
a. Both diachronic and synchronic metathesis of /r/ and a 
   following vowel are found.
b. Diachronic and synchronic /l/ metathesis were posited to 
    account for the derivation of present Bonggi forms from 
    proto forms and that of surface forms from underlying
    forms, respectively.

1. /r/ metathesis
a. Diachronic Process: /r/ metathesizes with a following vowel in an unstressed syllable if the vowel precedes an alveolar stop /t, d, n/. 
 
Putative proto-form
/ba.rat/  /ba.art/  ['baaRt^] 'west'  (Malay barat)
/Na.ran/  /Na.arn/  ['Na~a~Rdn]  'name'  (Dusun Naran)

b. Synchronic Process: /r/ metathesis is observed in affixed forms.
 
Root
ajar  ['aDaR]  'to teach'  /aDar/ + /On/  [E'DaaRdn]
-orod  'numb'  /m/ + /OrOd/  ['mO~O~Rd^]

2. /l/ metathesis
a. Diachronic Process: According to Boutin (2000), present forms of some Bonggi nouns can be derived from proto-forms by the interaction of five different phonological processes; 1) /l/ metathesis; 2) palatalization of /l/; 3) geminate reduction; 4) coalescence; 5) V preplosion.
 
Proto form     /l/ metathesis   /l/ palatalization   geminate reduction     coalescence     V preplosion
*dalan     'path' >      daaln >     daain >       dain >   [dajdn]
*talun     'forest' >      tauln >     tauin >     toin >   [tojdn] ~ [tejdn]

b. Synchronic Process: When the suffix '-On' is added to a stem ending in /l/, /l/ palatalizes to /i/ and /O/ is subsequently deleted. Boutin (2000) accounts for this in terms of /l/ metathesis, /l/-palatalization to [i] and vowel reduction.
 
Unerlying form /tOmbOl/ + /On/ 
/l/ metathesis tOmbOOln
Palatalization of /l/ tOmbOOin 
Tensing of mid vowel tOmbooin
Geminate reduction tOmboin
Offglide formation tOmbojn
Stress tOm'bojn
Neutralization  tEm'bojn
Labialization  tEm'bwojn 
Nasal preplosion  tEm'bwojdn 
Derived form [tEm'bwojdn]

Additional information:
a. Word final nasals 
  • When a preceding vowel is nasalized, word final nasals are realized as simple [m], [n], [N].

    •  
    onom /O.nOm/  ['OnO~m]  'six'
    mien /mi.En/  ['mi~E~n] 'aunt'
    tingaang /ti.Na.aN/  [ Ti'Na~a~N] 'scorpion'
  • When a preceding vowel is non-nasalized, word final nasals are preploded.

    •  
    agubm /a.gum/ ['agwUbm]  'type of shellfish'
    Sandahadn /san.da.kan/  [sEn'dahEdn]  'Sandakan' (place name)
    adakng /a.daN/  ['adEkN]  'charcoal'
