Iduna is anAustronesian language spoken onGoodenough Island ofMilne Bay Province ofPapua New Guinea.
The inventory of the Iduna language consists of 14consonant phonemes.[2]
| Labial | Dental | Palatal | Velar | Glottal | ||
|---|---|---|---|---|---|---|
| Plosive | Voiceless | t | k | ʔ | ||
| Voiced | b | d | g | |||
| Fricative | Voiceless | f | ||||
| Voiced | v | |||||
| Nasal | m | n | ||||
| Approximant | l | j | w | h | ||
Voiced plosives generally contrast with their unvoiced counterparts, except for the bilabial series, where/b/ varies freely between[b] and[p]. Moreover, the phoneme/g/ is commonly realized as[g], though for some speakers it may be pronounced as a voiced fricative[ɣ] without contrast. Finally,/t/ has also twoallophonic realizations:[t] occurs word-initially and word-medially beforenon-front vowels/a/,/o/ or/u/, whereas[s] only appears beforefront vowels/i/ or/e/.[3] Other minor allophonic realizations may occur. Among these variations only the last one is reflected in the orthography.
| Phoneme | Allophones | Context |
|---|---|---|
| /b/ | [b~p],[bʷ] | free variant;[bʷ] before non-syllabic/u/ |
| /f/ | [f],[fʷ] | Normally[f];[fʷ] before non-syllabic/u/ |
| /k/ | [k],[kʷ] | Normally[k];[kʷ] before non-syllabic/u/ |
| /g/ | [g~ɣ],[gʷ] | free variant;[gʷ] before non-syllabic/u/ |
| /t/ | [t],[s] | [s] before/i/ and/e/;[t] elsewhere |
| /d/ | [d],[tʰ] | [tʰ] before/i/ in final syllable position only;[d] elsewhere |
| /m/ | [m],[mʷ] | Normally[m];[mʷ] before non-syllabic/u/ |
There are fivevowel phonemes in Iduna.[2]
| Front | Central | Back | |
|---|---|---|---|
| High | i | u | |
| Mid | ɛ | ɔ | |
| Low | a |
Vowels have allophones too. The major allophonic variations are described in the following table. These include the double realization of/a/, which corresponds to[a] when found in stressed syllables, while it approximates[ʌ] in unstressed environments, and the nasal allophonic variant of/u/.[4]
| Phoneme | Allophone | Context |
|---|---|---|
| /a/ | [a],[ʌ] | [a] in stressed syllable;[ʌ] elsewhere |
| /u/ | [u],[ũ] | [ũ] following/m/;[u] elsewhere |
The language also has fourmonomoraicdiphthongs:/ai/,/au/,/ao/ and/oi/. These are distinguished from vowel sequences, which instead are bimoraic, e.g. the wordgiyauna[gi.jau.nʌ] 'he scrapes it' contrasts withgiyauna[gi.ja.u.nʌ] 'he unties it'.[5]
In Idunaconsonant clusters are forbidden; therefore, there are onlyopen syllables of type V, CV and CVV. Also, the special kind of sequence CuV is generally interpreted as CʷV.
The Iduna alphabet is shown in the following table:[6]
| A a | B b | D d | E e | F f | G g | H h | I i | L l |
|---|---|---|---|---|---|---|---|---|
| [a] | [b] | [d] | [ɛ] | [f] | [g] | [h] | [i] | [l] |
| M m | O o | S s | T t | U u | V v | W w | Y y | ʼ |
| [m] | [ɔ] | [s] | [t] | [u] | [v] | [w] | [j] | [ʔ] |
